We all remember that one magical summer that changed our lives.

For Joe, it’s 1999. School is over, and with zero idea of what he’s meant to do for the rest of his life, he’s reluctantly accepted a job at the local summer camp. Anything to drown out the sharp grief of missing his dad and move on from what school calls his "anger problems". But getting screamed at by hyperactive 10-year-olds is almost enough to make him quit on day one.

Almost.

Then he sees Amy Ashworth for the very first time, her black hair shining in the sun--and learns that nothing hits harder than first love.

She’s the only person he knows who reads for fun, or who’s seen Titanic 14 times. But there’s another side to Amy. Soon, she’s the only person he’s ever been to a wild house party with, or kissed under the twinkling stars. It’s the happiest Joe has ever been…until the terrible day when what’s left of his family fractures into a million pieces.

Caught up in Amy’s whirlwind, Joe can’t bring himself to tell the truth about his life. Would his dad have wanted him to fight for the girl he loves or protect his family no matter what?

Only one thing is certain: This is the summer Joe will grow up. But when he looks back decades later, will he be ashamed of his choices? And will Amy still be by his side?

Heartwarming, hilarious, nostalgic, and bittersweet, Truly, Madly, Amy explores first loves, last chances, and the summers that shape us. Perfect for fans of David Nicholls, Mike Gayle, and anyone who remembers the carefree days of being just 16, when the world was full of possibility.
