Jen Shaw has climbed all her life: daring ascents of sheer rock faces, crumbling buildings, cranes - the riskier the better. Both her work and personal life revolved around climbing, and the adrenaline high it gave her. Until she went too far and hurt the people she cares about. So she's given it all up now. Honestly, she has. And she's checked herself into a rehab centre to prove it.

Yet, when Jen awakens to find herself drugged and dangling off the local lighthouse during a wild storm less than twenty-four hours after a 'family emergency' takes her home to Cornwall, she needs all her skill to battle her way to safety.

Has Jen fallen back into her old risky ways, or is there a more sinister explanation hidden in her hometown? Only when she has navigated her fragmented memories and faced her troubled past will she be able to piece together what happened - and trust herself to fix it.
