I was a little afraid to start reading Boomerang, because I heard it was a comic novel and since English is not my first language, it isn't really easy to catch jokes, etc...
The first half of the book was really tough for me, although enjoyable. The second half was really pleasant, seeing how the history develops towards the end.
The best was Doreen. You cannot imagine how I hate her. Really! And this is, for me, the best way to agree that the book is really good.
