Let me apologize ahead of time. I must have read a different book from most of the previous reviewers. It has the same title and even some of the same action, but I missed the majority of what the other reviewers read. I will agree that the action is good when it is good. I will agree that the book has a great premise. But when the back cover blurb compares it to "a classic end-of -the-world novel in the tradition of Lucifer's Hammer",ARGHHHHH! (That's dinosaursese for "PU-lease!) About the only comparison I could find was the "dramatic personae" listing. This story has WAY to many characters and none as richly developed as Harvey, Tim, Maureen or Arthur. The time quilting premise is novel, although the explanation of the origins are a little fuzzy. The "fix" is worse than an angora ranch. What was the deal with "the group"? How did the moon and the future, etc. work it's way into the relevance of the story? Did the President's science advisor ever get anywhere with his theories? The cruise missiles fly, but what happened? Did the plan work? Was the science advisor right or wrong? Which science advisor had the correct theory? What happened to the Willamette, and so on? Did Atlanta cease its flux? There are way to many loose ends in this story. I realize that not everything has to be all nicely wrapped up at the end, but dang, there were more starts and stops than rush hour traffic! What happened to Kenny? Terry and Bill's excellent adventure to D.C., Huh? Let's go into a forest and explore and then when a T.Rex comes by and eats a few idiots, lets not get the hell out of here! The whole moon theory that just kind of lies there. The ending with Petra and Colter and the burying of notes, etc, I just didn't get the explanation. The sequence with the sailing family was great. The novel could have been so much better! I guess that's what editors are for. Compress the character list, snip off some extraneous story lines (the whole Hawaiian connection) and you have a leaner, meaner plot line. By the way, there was zero mention of what happened to the quilted areas that were shifted into the past. That could have been a great parallel story line. And just to be one, did you notice the footprints on the cover. I didn't realize that dinos hopped around leaving side-by-side footprints. Maybe it's just me. The moral of the story is be sure to have plenty of sugar on hand for any guests that might wander by, and oh, watch out for street gangs, I've read that they can be hazardous to your health.
