Definitely read Steve Hassan's book, next. His first book, 'Combatting Cult Mind Control' should not be skipped, IMHO. (One powerful aspect of reading this earlier book, is that you get to see his thoughts before he was even aware that JWs are a high-control group. You may experience some disbelief to discover that many other groups are identical to WT in their methods of control.)
Randy Watters has a book called, 'Thus Saith Jehovah's Witnesses' which I highly recommend. It's a collection of scans/photocopies of many, many WT lies -- from their own publications.
