100% solid perfection. Best creature/body horror I've read in months. A parasitic roundworm bioengineered and tested through some very unethical practices ends up running amok on Fallstaff island where a few teenage boys and their scoutmaster are on a weekend wilderness trip. I very much appreciated the writing style with PLENTY of character development, interviews with scientists/military, documents containing information about the worm, as well as video footage of some of the initial tests written out inbetween the events taking place on the island. All of it comes together in what I felt was a riveting horror novel overall. I will absolutely be reading more from Nick Cutter.
