Amigurumi World by Ana Paula Rimoli
Now available as a pre-order from Amazon!
I'll review the book when I can get my hands on it; meanwhile, you can check out Ana Paula Rimoli's Etsy shop (anapaulaoli.etsy.com) to buy individual patterns, and check out photos and free patterns on her blog, Ana Paula's Amigurumi Patterns & Random Cuteness. I've purchased some of her patterns and have crocheted the Owl Purse. The patterns are easy to follow, quick to crochet, and the results are adorable.
