I own loads of vegan cookbooks and this is one of my favourites. This isn't a healthfood type book, its full of vegan comfort foods and ways to make faux versions of things from scratch. The aesthetic is a messy zine style and its full of bits and pieces of drawings and random writings. Its not for the minimalist. The tone is friendly and fun.
Highly recommended, there're recipes for lots of things I've never seen in other books, eg. kofta balls (like delicious falafel but with shredded cabbage and cauliflower as well as gram flour). If you're into heat you'll enjoy the chilified hot-sauced focus, but you can always leave some of that out or cut back if you're not so into that.
Drawbacks - only things to say are its very American, so some ingredients will be hard to find in UK..but use your imagination! Also there's no index, but that means you get to trawl through the book all the more. There's also a boozer feel to the whole thing (hangover cures etc), so if you're straight-edge or teetotal this might irritate you.
In conclusion, buy it! It very very good.
