Knowing Caleb Carr only by his reputation for his previous two novels, I thought this might be an interesting introduction to his work for an old sci-fi buff like myself. I was wrong. The book is enticing enough with promise to keep one paging forward but it really never delivers. Nothing in it is new though it struggles to remain game and enticing with a real plethora of fake foreshadowing and come ons. I am only 3/4 of the way through and, though I intend to gut it on out, I will be extremely surprised if the end is any different from what I have already guessed it will be. If anything, this demeans the genre and I would respectfully ask Caleb to return to what he does best and leave the hallowed halls of Heinlein, Asimov, Pohl, Cherryh and the immortal Phillip K Dick undisturbed in the future.
