Cascade

The men around Volcanologist Lenaia Talavera have a habit of dying. As she struggles to process the tragedies, she pulls away from God and her boyfriend, Paleontologist Travis Perego. So when she's called back to Mt. Rainier and the small town of Mayim to investigate an act of sabotage, she jumps at the chance to avoid her problems and solve the puzzle. Someone on the mountain has tampered with the early warning system for rising magma, but who would want to risk an eruption that could kill an entire town?
Lenaia soon discovers that two women from town have disappeared. When she finds one of them dead on the mountain, she suspects the murder is related to the sabotage.
As she digs deeper, the evidence leads her to a deserted part of the mountain and an explosive secret. Unsure of who to trust and with time running out, Lenaia must stop a deadly plan before a killer buries the town of Mayim in a cascade of evil.
