Here's a fantasy novel that is mature without being gratuitous, magical without losing sight of the psychology of its characters, able to paint the world in shades of grey but brave enough to take a side. It pulls tricks on the reader and never once feels cheap. One third of the novel is in the second person, and it works! If you watched Game of Thrones with ambivalence and longed for something contemporaneous with the heightened social awareness of the 2000s rather than the sturm und drang of the 90s, this may be your best shot. Plus it deservedly won the Hugo Award this year, proving that even when the world seems to be ending there's hope somewhere out there.
