Crimson Deep

● "Something ancient has found new prey ... Us. Deep in the Florida woodlands, a pair of recreational divers are attacked and killed. Miles away, a research team captures an impossible sight on their remote-operated submersible. Meanwhile, a team of bank robbers speed toward their Florida hideout. As deaths mount, ex-sheriff John Decker is called from a much-needed vacation by a longtime friend, to help a baffled police department track an impossible enemy." ― quoted from this book's Amazon product page as of 2021-11-08.
