This book had some really laugh-out-loud funny bits along with a lot of somewhat boring story and fairly immature humor. It was along the lines of Hitchhiker's Guide to the Universe, but not as good, in my opinion. I think you have to like British humor to like either one.

There's a lot of joking around about time travel, death, etc. One of the main characters actually died near the beginning, but he lived on as a hologram simulation. At one point, he made a copy of himself because nobody liked him, and of course, he and his copy didn't get along either.

It was a fun read, but I started getting tired of it after the first couple of chapters.
