Valkyrie

"As one of Odin's Valkyries, Malin Krigare's greatest responsibility is to slay immortals and return them to the underworld. But when she unearths a secret that could unravel the balance of all she knows, Malin, along with her best friend and ex-girlfriend, must decide where their loyalties lie. And if helping the blue-eyed boy Asher enact his revenge is the risk to the world and her heart."--Provided by publisher.
