His Brother’s Mate by Maggie Tideswell

A witch, a vampire colony, a dragon shifter, and one little hotblood...

She doesn't belong there. She is just an ordinary 26-year-old girl with no special talents or superpowers, except for an affinity for sick animals.

Yet, suddenly, because she liked a guy she knew nothing of and wanted to explore her options for a future with him, she finds herself in a vampire colony with no way of escape. Her friend abandons her, leaving her at the mercy of his brother, who just happens to be the most gorgeous man she has ever seen.

She could not have foreseen what awaited her.
