The Killing Edge by Heather Graham

Chloe Marin survived a cult killing spree and helped police identify one of the murders. Police found both killers dead in a suicide pact. Since then, she has had to live with the ghosts of her friends begging her to avenge them.

Ten years later, searching for a missing model, Chloe confronts the woman’s ghost, who begs for her help. She teams up with Luke Cane, a British PI that has been hired by the missing girl’s father.

Together they race against time to uncover who is behind a new killing spree that seems to be centred on a model agency, but Chloe might be the killer’s actual target.

This is my first Graham novel, and it won’t be my last. Her writing is excellent, and her story was extremely suspenseful and fast-paced.
