Descending (Rising #2)

When Xanthus cashes in a long-standing favor, Kyros is faced with doing two things he thought he'd never do protect a mermaid and live on land. Dagonians loathe mermaids and Sara, Xanthus's wife is no exception. Also, a Dagonian standing on human legs? It's just not natural!

As is being around the vile creatures responsible for polluting his home and killing his sister wasn't horrible enough, Kyros has to deal with Sara's troublesome human friend, Gretchen. This beautiful, spunky human tries his patience and makes him feel things he shouldn't be feeling least of all for a land-walker! When Gretchen's life is threatened, he is forced to become her protector. But, there are two problems. First, how can he fight his attraction to her when he must keep her close. And second, when a mermaid wants you dead, no one can be trusted. Not even the ones you love."
