Summary: The book cries out for a sequel - a must read too!
Review: I was intrigued with this story right from the first few pages. It's a super sleuth story with a pretty good love angle and lots of action. Sam the hero is not your usual macho guy given the blend of back woodsy Native American mysticism woven into his character. It's a nice touch that take's him out of the crowd of action heros. In Overfall Sam is confronted with a number of brain altered people and sets about trying to discover the reason. He is hired by Anna, a celebrity, whose genius brother is suffering from an unknown ailment that soon takes on sinister overtones. Of course it turns out to be the tip of the iceberg and Sam ends up trying to unravel a far reaching plot while he tries to keep everybody important alive. Grady the ex-stripper is another unique and memorable character and Dun does a good job of bringing in another mind catching point of view.

Review: No Sleep. After page 50 of this book I could get no sleep. I'd shut the light off, lay there thinking about the story, turn it on and keep reading. I read the whole thing in one very long night and fell asleep at my desk the next day. Dun is really good at telling a story and keeping it going. Granted a few parts may be a little far fetched like the long opening action scenes. But hey, it's not hard to just go ahead and let yourself believe it. Dun comes up with enough critical details and a strong enough sense of the places and the people that he [draws] you in good. I have to minor complaints. First I think Dun could do a little more with Sam as far as character development and second I thought he could have made a little more out of Grady because she has the makings of a fascinating character.

Summary: Thoroughly enjoyed
Review: Overfall was a good enough read that I bought Dun's other two books. Although I liked Overfall the best the other books were definitely worth the read. Overfall has a compelling plot and fleshed out characters. The books is really about Sam a super-sleuth and Anna his Hollywood love interest. To me that would sound boring but believe me with all the bells and whistles Dun makes it fascinating. Anna as a character is not as intriguing as the other characters and especially Sam because people who have it made are never as exciting as those struggling to get there. Although Dun tells us that Sam is rich we never really lose our identification with him and Dun manages to keep him human despite some of his superhuman accomplishments. Although we're told he's a PHD business man with millions we don't really think about it and we tend to get caught up in his struggles anyway. This was a really different book that I thoroughly enjoyed.

Summary: Good novel. I recommend the book.
Review: Sam is a fanatic physical fitness guy who yanks a cigarette out of his protégé's mouth but is himself a closet smoker who secretly likes lemon sour cream pie. He makes his own cigars from Cuban tobacco leaves and he's a weird cross between a Native American mystic and a high tech super sleuth. Interesting combination. Sam is a good character but could be better developed and maybe he will be in the next book. Anna love interest is well done and I thought fairly realistic. Over all the plot moves and is interesting with lots of good factual development. The mystery is worth the wait and the science part is well done. If it's not based in some fact it sure sounds like it is. I notice there is a PHD in the acknowledgements.

Summary: With Dun you never know who is going to die
Review: Sam is a guy who loves women in general but has a bit of a hard time loving one in particular. He's got ice in his veins when it comes to being gutsy, but he also has some very human foibles. He's a closet smoker that decries smoking. He's pretty much disengaged from life when we meet him. Sam has a dozen or so identities and three deep identities complete with social security number. He's half-Tilok Indian, a bit of a wanna be mystic, clearly a male chauvinist and generally irreverent. In a bit of a disturbing departure from what you understand to be his character he goes a little new age and begins sounding like a sensitive human being. Dun manages to mostly salvage this in the end. Sam is a private eye on steroids. He has a legitimate government contracting business but also hires himself out for anti-terrorist work at exorbitant sums to various governments corporations and celebrities. In this story he comes out of retirement when he is thrown together with Anna a very public figure. Immediately she threatens his very private life when she takes more than a business interest in Sam. The beef in the story is a nifty new technology that has all sorts of lucrative and nefarious possibilities. Anna's brother Jason is a very peculiar kind of hostage essentially a genius at the mercy of a ruthless business man DuShane Chellis. But there are plenty of bad guys and we wonder which one will finally become the biggest of the bad. As in all his stories Dun moves the action at a terrific rate and there is a good romance.

Summary: action-packed thriller
Review: Sam is sailing his custom made vessel Silverwind off British Columbia when he sees a woman on South Windham Island jump into the water. The men on the supposedly uninhabited island make no effort to help her so Sam, risking his life, manages a daring rescue. His unexpected passenger is wealthy internationally famous movie star Anna Wade. She was on the island visiting her brother Jason who is employed by a shady company that is working on a top secret project that will be of interest to terrorists and third world dictators. Jason slipped her a heavily encrypted CD-ROM that she is supposed to deliver to a certain scientist. Sam, a free-lance intelligence agent, who is in charge of a computer with unlimited storage capacity, is sucked into helping Anna free her brother and also cure the sibling of what the people in Grace Laboratories did to his mind. OVERFALL is an action-packed thriller starring a very reclusive hero and a very exuberant heroine who strikes sparks off each other from the moment they meet. Their unusual courtship (for lack of a better term) eases the tension when the tale begins to boil and overcomes the coincidence of the rescuer having the perfect skills for this endeavor. A prime reason besides the action that David Dun's novels are so much fun to read is that he explains the science on a level that reader can understand without looking down at the audience. This book deserves a sequel because there is a very big loose end that deserves tying up. Harriet Klausner

Summary: If you like a thoughtful page turner you¿ll enjoy this one
Review: Sam Wintripp is a cool guy with an interesting way of solving high powered problems created by high flying criminals. He doesn't chase anybody but the best of the best and therefore we get the idea that he has to be the cleverest of the clever. This is a great mystery thriller although plenty wordy with lot's of action and a whole cast of bad guys who keep you guessing throughout. Dun gives the reader a myriad questions to puzzle over in this well crafted and somewhat unusual story. Dun loves the outdoor chase with man against nature and man against man and this book is no exception.

Summary: Mr. Dun hits the mark again.
Review: Sam Wintripp, recently retired from a lucrative private investigation practice, is sailing with his dog near the Queen Charlotte Strait when he spots a woman in the distance, running on a narrow trail above the shore. Chased by those who mean her harm, she plummets into the cold and angry water below. Somewhat reluctantly, Sam is drawn into action (and out of retirement) rescuing a Ms. Anna Wade, who turns out to be an Oscar winning, $20 million per picture actress. More importantly, Anna has some information regarding her brother that his captors (and her pursuers) want very much to retrieve. With this beginning, Dun launches into to a taut and well written thriller which is sure to please his growing base of fans. As with his prior two novels, there is a developing and believable romance between the primary players, Sam and Anna. But his latest novel is a bit more ambitious than the prior two -- broader in scope and ultimately more satisfying. Dun does a nice job with fairly complicated scientific elements and technical discriptions. As always, he avoids talking down to his readers, and puts his trust in their ability to keep up with the plot while following its scientific underpinnings. His characters are well developed, and he includes enough sub-plots to add interest and texture. Dun's writing in this latest effort is always good enough to draw the reader through the various plot twists, but at times it's even better than that, showing Dun's maturation as a thriller novelist. Overfall is another fine effort from Mr. Dun. With this thinking person's thriller, Dun shows again that tight plotting and well developed characters is the key to success. As a reader, it's nice to have someone new to turn to as "the formula" for some of the old standbys is beginning to get a little old.
