This edition was previously published under the ISBN13 9781523337941 Rian Field is living her dream as a Marine Biologist, but when she is attacked by a shark, it triggers memories from the past and changes her understanding of her present world. After surviving the shark attack, Rian Field continues her work at the Institute, determined to live her routine life. But as she attempts to cope with her growing post-traumatic stress outbreaks, she is plagued both by memories of an earlier trauma and a sudden onslaught of mysterious and ominous events. She soon finds herself immersed in an inescapable danger as she suspects that her former assailant is still threatening her life--and may be someone close to her; more disconcerting, though, is the growing certainty that the trauma is somehow connected to the shark attack, compelling Rian to uncover the truth of her past and discover who is after her.
