Legendborn

I love a retelling of Arthurian legends and updating to modern days or making the middle aged times more interesting. This book did not miss on making things interesting. A whole new kind of magic system (or at least knew to me as someone who unfortunately does not know much about African or afroamerican folklore) and the always current discussion about race, sex and class connected to your place in the world.
Without spoiling the end, but I absolutely did not see the ending coming, I thought it quite a brilliant plot twist - and cliffhanger for the sequel.
