Only a volcano can cure some things. Dr. Caprice Wilson, police psychologist, has spent her life unraveling the mysteries of the human mind - only to find herself in a deep crisis. Caprice prescribes herself a walkabout and goes hiking on Maui - but the solitary retreat she has in mind does not go as planned. Caprice faces an enemy she never knew she had and wrestles with questions of hope, identity, loss, and the nature of psychopathy in a cat-and-mouse game with survival at stake. "Toby Neal weaves a spell-binding suspense that pulls you in with breathtaking scenery, flawed characters, and brilliantly twisted psychology." Gae-Lynn Woods, author of the Cass Elliott Crime Series
