I actually got my book last summer, when couple of JW's came to visit me. I asked few questions about evolution and the answers that I got was... well, sad. The amount of misinformation they have is just sad. The book is way out of date, but I don't know any other books from Watchtower, that is dedicated to evolution.
To Leavingwt: I have seen those sites before and I am actually using them as a source to my critique. The misquatitions are pretty useful, since the quotes are quite old and I don't really find them anywhere anymore.
Talkorigins is also well-known site. Too bad that it's review is little short and not so detailed that I would want it to be.
I don't know when my critique will be finished. I am not a biology student or anything but I have been thinking to give my "book" for check to couple of my friends that actually know something about evolution and biology. Maybe someday I will post my work here others to see.
