Seven lighthouses. One ancient prison. Something very patient waiting to get out. The Deep Hunger has been sealed beneath the ocean for eight centuries. Now the lights are failing, the keepers are dying, and ships are being dragged into the dark. Kira and her new guild have one chance to restore the Stormwatch Lighthouse before the binding breaks. But the caves are crawling with the Hunger's children—and the real enemy is the man who was supposed to hold the light. Some betrayals start thirty years before you ever see them coming.
