Immortal's End Series by Elizabeth Myrva

Her enemy, his forbidden mate, and the war that brought them together. Slave. Monster. Huntress. Raven has lived under the weight of many names and none at all. What she’s never had is freedom, and now that she’s stolen it, she’ll do anything to keep it. Even if that means getting close to the very beasts she was trained to kill. Claiming a drunken one-night stand was never how Logan intended for his night to end... moreHer enemy, his forbidden mate, and the war that brought them together. Slave. Monster. Huntress. Raven has lived under the weight of many names and none at all. What she’s never had is freedom, and now that she’s stolen it, she’ll do anything to keep it. Even if that means getting close to the very beasts she was trained to kill. Claiming a drunken one-night stand was never how Logan intended for his night to end. He especially hadn’t expected the perfectly human-smelling woman to run off before he could get her name, but now that she wears his mark, there’s no going back. They’re irrevocably tied together, and it’s clear that she has secrets. Vampires and Lycans were born to fight, but they'll be forced to help each other save those they care for most. Who knew war could breed such tempting enemies? Welcome to Immortal's End. less

A lifetime of hellish training under the Church’s cruel hand could have never prepared Raven for love. Nor could it have ever prepared her for the truth. She's not an Aphotic. But knowing that doesn’t erase the numbers on her cheek or her bloody past. Two things Logan’s terrifying father isn’t likely to forgive.
