What if saying hello to an old friend meant saying good-bye to life as you know it?

It’s been six years since Pen Calloway watched her best friends walk out of her life. And through the birth of her daughter, the death of her father, and the vicissitudes of single motherhood, she has never stopped missing them.

Pen, Cat, and Will met on their first day of college and formed what seemed like a magical and lifelong bond, only to see their friendship break apart amid the realities of adulthood. When, after years of silence, Cat - the bewitching, charismatic center of their group - e-mails Pen and Will with an urgent request to meet at their college reunion, they can’t refuse. But instead of a happy reconciliation, what awaits is a collision of past and present that sends Pen and Will, with Pen’s five-year-old daughter and Cat’s hostile husband in tow, on a journey across the world.

With her trademark wit, vivid prose, and gift for creating authentic, captivating characters, Marisa de los Santos returns with an emotionally resonant novel about our deepest human connections. As Pen and Will struggle to uncover the truth about Cat, they find more than they bargained for: startling truths about who they were before and who they are now. They must confront the reasons their friendship fell apart and discover how - and if - it can ever fall back together.
