Louise, a single mother, has an affair with her new boss, David, and secretly befriends his wife, Adele. Adele teaches Louise lucid dreaming to manage night terrors, and Louise starts to suspect David is controlling his wife. Flashbacks show Adele's time in a psychiatric clinic, where she met Rob, a troubled young addict.

What Happens at the End of Behind Her Eyes

Louise learns that Adele can leave her body during sleep. She discovers that Rob, after learning the trick, took over Adele's body and murdered Adele in his.

Who Will Like This Ending

Readers who enjoy endings that are shocking will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how Sarah Pinborough closes the story, which is exactly why many readers look it up.
