Query: review for reef of death

I recommend this book to anyone who likes horror and action. An example of horror is when the sea creature has killed Arnhen and is now ripping him to shreds. "It snapped at them as the girl saw Arnhem's torso float up to the surface, saw the white flash of spine and the circle of shredded, raw flesh." An example of action would be when Dr.Ecenbarger put a guard in the torture chair. A crab was put in a cage and then the cage was put on the guard's head. "The guard was dead only moments before the crab began the feast on his brain." In conclusion, I think anyone who likes horror stories and action, should read this book.
