Fateful Series by Cheri Schmidt

A huge fan of Jane Austen, Danielle hopes to find her own Mr. Darcy when she leaves Colorado to attend art school in London. Of course she knows it's silly to wish for that, naive even. But she's met enough males who lacked respect for women, a growing trend it seemed. And at nineteen...well.... However, on only her second night there she gets lost and is threatened by a stalker who proves to be immune to her martial arts training. Before she is completely overpowered, she is then saved by Ethan Deveroux.

While Danielle does find the romance she seeks in Ethan, he's no Mr. Darcy. Her hero is held by a spell which fractures their chance at a happy ending. During the day Ethan is closer to mortal than immortal and can date her like any other man. Yet, as the sun sets, the powerful magic of an ancient curse returns and the evil of that spell is revealed. When that magic begins, Danielle's fairytale romance ends because Ethan Deveroux is a vampire. 

The Fateful Trilogy continues with Fractured. No, it’s not called Fractured because Ethan and Danielle break up...in case you were wondering.

They had thought they’d escaped most of the danger surrounding them, when in truth they’ve made it worse by unintentionally sparking a civil war amongst vampires. Many vampires want to protect them for discovering the cure to the curse binding their kind. However many more want to destroy them for that same discovery.

Ethan’s and Danielle’s struggle for survival intensifies while they sink deeper into the midst of this danger. The romantic fairytale bliss they once had will soon fracture under the pressure of the curse....
