Mother-Daughter Murder Night by Nina Simon

NEW YORK TIMES BESTSELLER - REESE'S BOOK CLUB PICK
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 sleepycoastal 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. 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, Lana 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 amateur 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.
