The demons seem to be attached to St. Adrian's, but Dani and Tommy are not sure how. Quinn believes that contamination of Tommy's pond is due to chemicals Linz Pharmaaceutical is manufacturing and planning to distribute. Tommy and Dani know that they must try to get more information by getting into St. Adrian's and Linz, but it's a dangerous mission.
Fatal Tide is an outstanding ending to the trilogy. I liked it better than any of the other books. Tommy and Dani have resolved their differences and their love is blossoming. Quinn and Cassandra are strong characters who risk their lives to help. Reese, is a frightened boy, who is trying to decide who he can trust. Their interactions very realistic and add depth to the novel. I love Tommy's interest in gadgets that end up saving their lives.
If you haven't read the first two booksof the trilogy, I recommend that you start. This book can stand alone, but it is much better read as part of the set.
I reviewed this book for the Thomas Nelson Booksneeze Program.
