i had read this series called "underland chronicles" by suzanne collins. i LOVED the series, it was AWESOME!!! the only thing i hated was that the last book's ending SUCKED!! it's was complete CRAP! Gregor (the main character) had to leave Luxa (the love of his life) and his flier named Ares (his bond who's a huge bat. if you haven't read the series, this won't make any sense) died! it was completely horrible! so now my friend is writing an alternate ending. it's MUCH better.
