Natalie Donovan thought she knew her father better than anyone. So when he goes missing on a fishing trip, leaving behind only his overturned kayak and a broken family, she refuses to believe he's really gone. At first, everyone thinks it was a tragic accident. But as the days pass, unsettling clues surface—clues that suggest he might not have drowned after all. And the shocking possibility that her dad's somewhere across the world, alive and starting over with someone else. Determined to uncover the truth, Natalie hatches a plan to track him down, even if it means taking a "gap year" she never planned on. Armed with nothing but her dad's last known location and her best friend, Ryan Maxwell—the tech enius who's secretly in love with her—Natalie sets out across Europe, chasing shadows and half-truths in an attempt to find the man she thought would never leave her. But as they dive deeper, Natalie and Ryan find themselves swept into a world of scams, secrets, and a dangerous game of cat-and-mouse that no one warned them about. And when she finally catches up to her dad, the truth is far more twisted than she ever imagined. Will Natalie ever be able to forgive him? Or will the journey force her to let go of the past and start writing her own future? The Last Summer I Remember is a story about the lies we tell, the people we love, and the lengths we'll go to find out who they really are.
