Crimson Horizon (Blood of the Sea Book 1)

When Lavinia Maycott's home is attacked by villainous pirates, she isn't sure how to find peace being a survivor. With her family murdered, she has only one place to go. However, her betrothed's estate isn't the safe haven she was expecting. 

Alone and running for her life, she finds acceptance with a small group of rebels intent on fleeing the island in search of safer territories. When that proves more difficult than any of them realize, Lavinia must chose between letting harm come to her new friends or sacrificing herself to save them.

It will take all of the courage Lavinia didn't know she had to make it off the island alive, but even then, vampires and pirates roam the seas, making nowhere safe.
