Fantastic book, cheeky, refreshing, funny and smart! I would say it's even better than Gallagher Girls series. Rest assured, peeps, no boy trouble here, no drama or any sort of idiocy.
Kat is brave, very clever, responsible and holds her team of miscreants aka professional thieves together like a superstrong glue :) It was actually a perfect YA. Serious motives, real problems, plenty of action, endless amount of fun and lack of stupidity. Highly recommended.
