When Val Sherwood and her friends went for a hike with the Sunset Hills Ecology Club, they didn't expect to see more than the usual wildlife. But when stories told around the camp fire came true, Val had to find a way to live 'til morning. The first published work by the award-winning and best-selling team of Debra Doyle and James D. Macdonald, reprinted here for the first time, "Bad Blood" inspired a series of three young-adult horror novels.
