Rick Riordan is good, even though he's a children's author mainly. Life of Pi is good too, the original novel the recent movie was based on. Read the Hitchhiker's Guide to the Galaxy by Douglas Adams, it is awesomeness in its most awesome form in the awesome history of sheer awesome awesomeness.
Yeah. It is pure awesomeness. Did you also read the rest of the pentalogy (however you spell that)? I love Adams's sense of humour. Everybody in the class knows that I celebrate Towelday and 42 day (my personal invention, on April the 2nd). It will be greatly appreciated if you do not panic.
