Abducted - T.R. Ragan

Abducted is the first novel in the Lizzy Gardner series. No cliff hangers though. Just a good ending.

When a serial killer called Spiderman was killing teenage girls, Lizzy Gardner was the one who got away. Now Lizzy is determined to help women protect themselves from the kind of predator who kidnapped her. But Spiderman was never caught and Lizzy has spent her whole life waiting. Now is the time. Spiderman is back, and Lizzy is his target. This time she's ready. Very highly recommended.
