This is without a doubt the worst Clancy book I have read. I bought Bio-Strike because I loved his previous Power Plays work, Shadow Watch. This book was slow getting set up. I felt this took up at least half the book. It finally got pretty interesting, but then Clancy hung the ending. I don't mean he left it open to an interesting sequel; there was no closure to this story, and I don't look forward to reading a continuation of it.
