From the New York Times bestselling author Kristin Hannah comes a powerful novel of love, loss, and the magic of friendship, soon to be a major Netflix series.
To the people around them they were known as KateandTully or the Firefly Lane Girls. A single, inseparable unit. Best friends forever. On the surface they were as opposite as two people could be: Kate, doomed to be forever uncool, with a loving family who mortifies her at every turn. Tully, steeped in glamour and mystery, but with a secret home life that is destroying her. Yet they are best friends who swear they'll be there for each other, and for thirty years that promise holds strong—until events and choices in their lives make that promise impossible.

Firefly Lane is a novel for anyone who ever drank Boon's Farm apple wine while listening to Abba. It's a novel for anyone who ever had someone who knew you better than you know yourself. It's more than a coming-of-age novel—it's the story of a generation of women who were both blessed and cursed by choices. It's about promises and secrets and betrayals. And ultimately, about the one person who really, truly knows you—and knows what has the power to hurt you and heal you.
