Query: A roller coaster ride of a book!!

What can I say - this book left me breathless! Part corporate satire, part esoteric romp, part love story - funny, sad and suprisingly thought provoking.Cat has lost her high-flying job and the man she was in-love with, and now she's out for revenge. But the underlying message in the book is this - by getting revenge on those in her past, is she just creating more bad karma for the present and future?This is clever and page-turning read, with well thought-through characters and identifiable, not ridiculous situations. Makes you wonder about your whole life and whether your wrong-doings may come back to haunt you... I loved this book and have recommended it to all my friends.
