About The Book

An “edge-of-your-seat” (Jessa Maxwell, author of The Golden Spoon) thriller about three women with dark secrets whose lives intersect in the picturesque and perilous Yosemite National Park from the USA TODAY bestselling author of Please Join Us.

Equipped with a burner phone and a new job, Cassie Peters has left her hectic life in New York City for the refuge of her hometown of Mammoth Lakes, California. There, she begins working again with Yosemite Search and Rescue, though she is still haunted by a case she worked on a decade ago.

She quickly falls into old patterns, joining a group of fellow seasonal workers and young adventurers who have made Yosemite their home during the summer. There, she meets Petal, a young woman living in a trailer with her much older wife, keeping a detailed diary of the goings on of the park, and Jada, a recent college graduate on a cross-country road trip with her boyfriend, documenting their journey on Instagram.

When these three women cross paths, Cassie’s past catches up with her, and the shocking consequences ripple out far beyond what any could have imagined. “Taut and atmospheric with as many jagged peaks and valleys as its dramatic setting, this captivating page-turner will keep you guessing until the end” (Katherine St. John, author of The Vicious Circle).
