Thunder Snow has been trained by her tribe to be a scout—a trained spy. She's put all her energy into being the best scout she could, eschewing friendships and romance. But when she's called on her first assassination mission, she is betrayed by the person she trusts the most. Now on the run, Snow must learn techniques half-bloods aren't supposed to learn. She must use everything from her training to avoid those who hunt her, and face the one who wants her dead. NOTE: This is a standalone novella - none of the books in the series need to be read in a particular order.
