john saul is turning out to be a bit hit and miss for me, but this story was a good read. the ending was slightly dissapointing which it seems is a regular theme for john saul in the books ive read so far (except shadows) but all the same closes the story satisfactorily.
the cover and title are a little misleading, in that this is more a medical/sci fi thriller rather than a horror but it still packs a punch.
interesting concept and likeable characters keep the momentum and result in an entertaining read.
as with most of john sauls books, hes not afraid to kill off characters/children so not one if you are sensitive to younger people in peril (in this case teens)
