Ocean Depths: A Time (Hardcover) (ISBN-13: 9781532012693)

While Callista Sunders recovers in a hospital room from an unexpected accident, hopelessness fills the crack in her heart and only love can repair the fissure. Love is something she never thought she would find outside of her Grandma Anne, her mother, and her twin brother--until she met Lord Triton. But now he is missing and Callista fears the worst. All she has is his sigil that she wears around her neck and the hope that one day they will be reunited.
Callista never thought she'd be spending her eighteenth birthday in the hospital, but when she receives Triton's journal as a gift, everything changes. While studying it with Grandma Anne, Callista finds a spell designed for time travel. Anne, along with her coven attempt to send Callista back in time to the island they know as Pitcairn. If it works and she survives, Callista will know Triton, but to him, she will be a complete stranger.
In this continuing tale, a young woman must use her special abilities and a time travel spell to find Triton, a merman deity who needs her help, and she, his.
