1) The School for Good and Evil by Soman Chainani
We both really, really love this map. Neither of us have read this book yet but this map definitely increases our urge to do so soon! The towers on the map all say things relevant to evil or good (like Valor, Charity/ Vice, Malice) and the swans at the bottom look amazing.
2) Swallows and Amazons by Arthur Ransome
Our mother actually nominated this one and I have to agree. Its so pretty. Plus we have a tiny little bonus map of Wild Cat Island at the top of one of the pages which is cute.
3) Game of Thrones by George R. R. Martin
Not a great picture (sorry) but it is a great map.
4) Magyk by Angie Sage
5) Throne of Glass by Sarah J. Maas
In the spirit of I-can't-wait-for-Queen-of-Shadows here is the map from Throne of Glass!
