For fans of Fleishman is in Trouble and Such a Fun Age, an electrifying novel about six longtime friends whose tropical vacation is interrupted by an unexpected crisis, forcing them to ask how strong their bonds really are

Clare is supposed to be the grown-up one. Married to the love of her life, with a major deal for her first novel, she has everything she thought she wanted. So then why does it all feel so wrong? When she agrees to a weeklong vacation with five of her oldest friends, she is hoping for an escape with the people who know her best. There is Jessie, who won’t stop talking about her new boyfriend; Mac, trying to pretend he hasn’t outgrown the group; Kyle, the eternal peacemaker; and Renzo, who brought them all together but keeps picking fights. And then, of course, there’s Liam, the guy Clare has barely seen since high school but somehow can’t get out of her head—or her bed.

But when a terrifying news alert shatters their peace, it becomes harder to ignore how much the world has changed since they were teenagers. As the resentments and tensions that have always simmered just beneath the surface begin to boil, Clare must ask if their shared history is enough to sustain their friendships, or if growing up might mean letting go.

With crackling wit and emotional fearlessness, When We Grow Up is a provocative portrait of friendship in a world that feels ever more unrecognizable and a searing exploration of what it means to be a good person.
