Tamsin is a Valkyrie, a clandestine breed with some serious cred in the Fae world. She is cool, kickass, and more skeptical than most when it comes to everyone's favorite Succubus, Bo. Tamsin is here to make nice and play by the rules, but her loyalty and trust is not so easily won over. And though her powers are as mysterious as her past, there's no doubt that you'd want Tamsin by your side in a bar-brawl.
