The main character is recruited by a University to conduct historical research in secret using time travel. 
 For a book involving time travel it doesn't deal with paradoxes and except for the Cretaceous period, very little of the story takes place in the past. Plot plays like a disaster movie, if anything can go wrong it does and often. A large part of the book deals with the main character relationships and life at what comes off as a party school. Read more like a coming of age disaster story then thought provoking. 
 Told in reflective first person perspective with plenty of dry wit and self depreciating humor, personally I found it often hilarious. There are many side characters and about half way I started losing track of them. The story shifts and twists a few times the ending opens up sequels/series to a new direction. 
 It's a fun read and I got through it quickly but besides a few cool concepts not much to reflect back on or thought provoking. I'll probably read the sequel.
