What could be more exciting than a girl being stalked by an obsessed, deluded admirer? A girl being stalked by an obsessed, deluded admirer who has an obsessed, deluded girl in love with *him.* No wonder the detectives and Alex were getting confused when they couldn't pin Cassie's attack on her stalker. A lunatic stalker believing himself to be in a non-existent relationship with her, they could comprehend. But *another* lunatic believing herself to be in a non-existent relationship with the stalker... a love triangle has never been done this way before.
It's hard to tell which is more exciting: the suspense- and action-filled plot, the frightening climax when Cassie gets shot, or the utterly unexpected ending complete with the girlfriend's creepy line.
Olivia: What are you doing here? ... ... ...
"I had to take a shower."
