A hilarious and thought-provoking murder mystery about the death of a friendship, and one woman’s quest to track down the best friend who disappeared, for fans of Where'd You Go, Bernadette.

Isabella’s NOT dead.

That’s what Gwen tells anyone who asks about the friend who ghosted them all fifteen years ago. But if Isabella’s not dead, then where is she? And why did she leave, just when Gwen needed her most?


Freshly fifty-three, out of a job, and with children who are starting to fly the nest, Gwen decides to turn detective. Setting out to solve the mystery, Gwen embarks on an adventure across England—then across Europe—that will test her marriage and put her on a collision course with reluctant acquaintances, a mother-in-law best described as eccentric, and a rabbit hole full of clues. But Isabella’s not the only one who’s lost.

A tale of deep, frayed friendship, fractured memories, and skewed perspectives, Isabella’s Not Dead is the story of one woman’s quest to reclaim her best friend—and herself.
