The Vanishing — Jayne Ann Krentz

From New York Times bestselling author Jayne Ann Krentz comes a new gripping romantic suspense trilogy fraught with danger and enigma.

Forty years ago in the small town of Fogg Lake, "The Incident" occurred: an explosion in the cave system that released unknown gases, causing peculiar effects on its residents, such as strange visions and ominous voices. Not wanting the government to get involved, they chalked it up to the hallucinogenic effects of mushrooms. Little did they know these effects would linger through the generations....

Residents Catalina Lark and Olivia Dayton have been best friends for years and own an investigation firm together, using what they call the "other sight" to help with their business. When Olivia goes missing, Cat frantically begins the search for her alone when the town does nothing about it. When scientist Slate Trevelyan shows up, she has no choice but to accept his help even though there's something about him she just can't trust. The duo discovers someone is hunting the two witnesses of a murder in Fogg Lake fourteen years ago--the very one Cat and Olivia witnessed as teens, one that they couldn't prove happened. Cat and Slate's search for Olivia takes them down a rabbit hole that is far more dangerous and mysterious than they ever expected, and with a killer in their midst, neither of them can foresee who will come out alive.
