Childhood friends (re)discover one another after a startling request reunites them in this exhilarating, tender, and witty story from the #1 New York Times bestselling author of The Bookstore Diaries.

Some friend requests can't be denied...

Through high school and college, only children Lily, Anne, and Maya vowed to be each other's family. The Onlys became as close as sisters...until Anne married the man Lily loved. And it tore them apart.

Now Maya has a plan to reunite the Onlys. Using the ultimate guilt trip, she coerces her besties into a series of quests to recreate memories they should have made together. Somewhere between the girls' trip to Vegas and the too-hot-for-turkey Fakesgiving, Lily and Anne begin to understand each other, their complicated past--and their beloved friend--in a whole new way.

If they can forgive their younger selves, maybe those old wounds can finally heal, and the Onlys can step into the future with a stronger bond than ever.
