Quite simply the best crochet book I have! Buy it, you won't be disappointed. I've looked through quite a few Amigurumi style pattern books and this one beats the others hands down. You can tell the author really loved making these designs. Each character is beautifully pictured and given a whimsically funny back-story that links it to some of the other designs, so the book is a pleasure to read as well as to crochet from. Everyone I've shown it to has been captivated.
The patterns include farm animals (chickens, goat, cow, etc), a couple of people, pet animals (mice, guinea pig, cat, dog, fish, etc), exotic animals (koala, emu, lion, alpaca, etc) and even a short Christmas section (reindeer, fairy, etc). There's not a single duff creation in the book, and the instructions are easy to follow. If you want to duplicate the effect achieved exactly then it's easy to get the yarns used (mostly Rowan), and the patterns are in UK English so there's no confusion over terminology.
If you're an absolute beginner you'll probably need a helping hand, but anyone who can manage plain double crochet should have no trouble, so long as you remember to use a marker for the beginning of the rounds.
