Ariston Dago is a sentry, a protector for his people. He watches the waters of his territory, keeping his god and his race safe both above and below the murky depths around Venice, Italy. When he’s compelled to save a human that falls from a transport, his life is forever changed, because the human he saves, Teagan Moss, is his mate, the first human to ever mate a Dagonite. Teagan Moss is the kind of woman to shoot first and then question the body later. When she wakes with a Hydro bomb strapped to her body, she knows someone is going to pay for trying to kill her, and that she is going to need the help of the sexy exotic Dagonite to find out who exactly needs that bullet in their brain. What she doesn't count on, is the scorching attraction she feels for the male who is so certain she is his. Thrust into solving the mystery surrounding the attempt on his mate’s life, Ari and Teagan uncover more than the answers they are looking for, and the truths they unearth could send the world into another war.
