From the New York Times bestselling author of the runaway hit Mother-Daughter Murder Night, a Reese’s Book Club pick, comes another fun, family-centered whodunnit about two sisters who work together to find a killer as they raft down the rapids of the Grand Canyon.

What’s a family vacation without a little murder?

Liv and Mandy Chisholm’s yearly sister trip is a sacred tradition, an attempt to bond as their lives increasingly diverge. Liv, the ever-practical older sister, packs the color-coded itineraries. Mandy, a bedazzled human tumbleweed, brings the spontaneity.

This year, the sisters take off for a rafting adventure through the breathtaking depths of the Grand Canyon with a group of strangers. But beyond the terrors of whitewater rapids, sibling squabbles, and rogue reptiles, the ferocious beauty of the river carries a darker undercurrent, and an unexpected guest: a murderer in their midst.

When a fellow traveler is found dead and another corpse hits the water, the rafting trip flips from idyllic sister vacation to high-stakes murder investigation. Every suspect has a secret, every clue is drenched in mystery, and Liv and Mandy can hardly trust each other, let alone their own instincts. With the river raging and danger around every bend, the Chisholm sisters must work together to catch a killer—and keep their relationship from capsizing—before it’s too late.

Nothing brings a family together like a murder next door.

“I just loved how intriguing the mystery is but also the dynamics between a grandmother, a mother, and a teenage daughter.” —Reese Witherspoon

Think: Gilmore Girls, but with murder.

High-powered businesswoman Lana Rubicon has a lot to be proud of: her keen intelligence, impeccable taste, and the L.A. real estate empire she’s built. But when she finds herself trapped 300 miles north of the city, convalescing in a sleepy coastal town with her adult daughter Beth and teenage granddaughter Jack, Lana is stuck counting otters instead of square footage—and hoping that boredom won’t kill her before the cancer does.

Then Jack—tiny in stature but fiercely independent—happens upon a dead body while kayaking, stumbling into a complex small town murder. She quickly becomes a suspect in the homicide investigation, and the Rubicon women are thrown into chaos. Beth thinks Lana should focus on recovery, but Lana has a better idea. She’ll pull on her wig, find the true murderer, protect her family, and prove she still has power.

With Jack and Beth’s help, this trio of amateur sleuths uncovers a web of lies, family vendettas, and land disputes lurking beneath the surface of a community populated by folksy conservationists and wealthy ranchers. But as their snooping advances into ever-more dangerous territory, the headstrong Rubicon women must learn to do the one thing they’ve always resisted: depend on each other.
