First of all I must say that I enjoy Child on his own more than his collaborations with Preston even though their books are enjoyable as well. This book is not on the grander scale that their books usually are, its more of a play with some homicide and technology thrown in the mix. The story is interesting even though its not especially original but Child writes the characters well and the tension is there through out the book. As other has mentioned its not hard to figure out who the culprit is but I dont think it is a big problem because I want to know how the characters get to the conclusion and as I mentioned Child manages to hold the suspense level almost to the finish. I reco the book but if there is only one book you should read by Child you should go directly to Deep Storm which is a much better book in my opinion.
