The central conflict of Book 3 begins when Conrad finds out about the engagement. Unlike the previous books where Conrad was aloof, here he is desperate. He tells Belly that Jeremiah cheated on her during a fight at a party (a revelation that destroys Belly’s trust).
The book shifts into a race against time. The wedding is planned for the summer after senior year, and the entire family—Laurel, Steven, and the ghost of Susannah—must watch the love triangle play out with wedding rings at stake.
Belly has always romanticized the idea of "The Summer" and "The Boy." This book forces her to distinguish between the fantasy of a wedding and the reality of a marriage. She learns that a ring cannot fix a broken foundation of trust.

After the emotional rollercoaster of It’s Not Summer Without You, the third book picks up two years later. Belly is now in college, dating Jeremiah — and shockingly, they’re engaged. But as anyone who’s followed the love triangle knows, Conrad is still very much in the picture. book 3 the summer i turned pretty
What works:
Han does a fantastic job showing how the characters have matured. Belly is less naive, Jeremiah’s easy charm is tempered with real flaws, and Conrad’s brooding intensity finally gets the emotional depth it deserved. The shifting perspectives (Belly and Conrad both get chapters) add layers to the decades-long family drama. The beach house feels more like a character than ever — nostalgic, comforting, and heartbreaking all at once.
What might frustrate you:
The engagement plot feels rushed and a bit dramatic, even for YA romance. Some readers may find Belly’s indecision exhausting by this point. And if you’re firmly Team Jeremiah, the ending will sting — the resolution leans heavily into “endgame” territory that was telegraphed from book one.
Final verdict:
If you’ve come this far, you need to finish the trilogy. We’ll Always Have Summer delivers the closure you want, even if it’s not the one everyone will love. It’s messy, emotional, and deeply satisfying — a fitting farewell to Cousins Beach. Have tissues ready.
