Team Grendel is out of options. With a mysterious enemy destroying their refuges, the crew of the Beowulf III is forced to seek sanctuary on an island that wants nothing more than to kill them all, an island that is pure death and evil. While Ballantine struggles to find them a less deadly option, Team Grendel must risk their lives to help a teammate. Something is wrong with Darby and an answer must be found before it is too late. But finding that answer may mean not all of them will make it out. Fear! Death! Terror! Blood! Nothing is right, nor will it ever be again, when Grendel and the crew land on Murder Island.
