Three drownings, one eclipse, no explanation. In the eerie town of Crescent Cove, the annual eclipse brings thousands- but this year, for the third year in a row, it brings death. Delilah Groves is the third body pulled out from the lake. Her death ruled a suicide. But those who know her aren't convinced. A grieving friend begins to investigate, and uncovers a strange pattern stretching beyond coincidence. The deeper he digs, the more apparent the truth becomes- these deaths were never suicides. They were something far worse. Someone is watching and waiting, and they won't stop until the entirety of Crescent Cove is pulled under.
