Jennifer Hillier's Creep ($8) is a devilishly addicting read about a scandalous love affair gone wrong, made illicit by the fact it's between a psychology professor and her graduate student. Ethan isn't ready to let Dr. Sheila Tao go, and he's ready to do anything — even if it means killing a fellow classmate — to prove Dr. Tao made the wrong decision in breaking things off.
