I'm pretty new to this myself. Just started a little over a month ago, but already have 3 batches going.
My first book was "Radical Brewing" by Randy Mosher (Radical Brewing.com
). Highly recommended. Not really a how-to book, but definitely inspiring and provides lots of interesting context and background.
I've also heard great things about "How To Brew" by John Palmer
. I've ordered it and its on the way as my next read.
