Title: Three Dark Crowns
Author: Kendare Blake
In every generation, three queens are born - triplets. Each has a different power - poison, nature, and the elements. Then when they turn 16, SHIT GETS REAL. There can only be one queen, so they all try to kill their sisters.
There is no clear protagonist here, which I like. The Poisoner starts out pretty wimpy but by the end I was like "DAMN that chick is a BADASS!"
There's a plot twist at the end, but it didn't piss me off like twists usually do.
You should buy this because it's awesome and the cover is pretty.

Full disclosure: I bought it with my own dollars.
