Cause to Kill by Blake Pierce

Rating: WARTY! "Haunted by a tragic mistake..." - here we go; what detective novel doesn't feature a main character with a haunted past? Yawn. "...homicide detective Avery Black seeks redemption when a serial killer begins terrorizing college campuses. But her investigation could see her colliding with a monster as brilliant as she is." When doesn't the detective collide with a monster in these stories? What? The serial killer is really a nice guy? Now that would be a twist, but as it is, it's the path most traveled and boring as all get out.
