Review of "Fatal Tide" by Iris Johansen

Our main character here is one Melis Nemid. Melis lives on an island in the Caribbean where she conducts her research on dolphins. She is also escaping a nightmarish past. On the island, life is peaceful, and Melis and her Dolpin have forged a friendship. Her tranquil existence is about to be shattered by a killer who is on the prowl. One person who can help her is a fellow oceanographer who gets close to her and gains her trust. He wants to learn the secrets of her past. Her dolphin is quite special and comes from an area in ocean where there is an undiscovered deep-sea mystery. Danger comes so close to Melis that she finally agrees to pack up the dolphin and travel back to that part of the sea where the mystery is located and only the dolphin can find it.

Its a very exciting adventure mystery in which the dolphin becomes a major character.
