I know everyone will already have recommended this, because who isn't a massive Made in Chelsea fan, but I really like Lucy Watson's Feed Me Vegan cookbook.
To be honest I had no clue who she was but a foaf sent me a vegan brownie recipe and it was amazing. I bought it on the strength of that recipe alone and was not disappointed. I've made loads from it and enjoyed them all, which is rare for a cookbook. The only down side is that some of the recipes use vegan cheese, which is something I'm not in the least bit keen on.
