Never Vacation with Your Ex by Emily Wibberley and Austin Siegemund-Broka
Recommended: sure
For a story where you know what’s coming and that’s part of why you enjoy it, for a character who is afraid of commitment in a way I haven’t often seen in main characters especially in young adult novels

Summary
Seventeen-year-old volleyball star Kaylee Jordan lives a life of player rankings, constant training, and a carefully curated social media full of followers watching to see if she’ll go pro out of high school like her famous mom. Her one refuge, and the thing she looks forward to every summer? The vacation her family spends in Malibu with the Freeman-Yus.
This year, there’s only one problem: Kaylee and their son, Dean, dated for the past three months, and Kaylee just unceremoniously dumped him. Hoping to spare them the worst summer ever, Kaylee comes to Dean with her unconventional solution: she’s going to walk him through her rules for getting over an ex. When Dean grudgingly cooperates, Kaylee’s got her work cut out for her.
But helping Dean follow her own rules starts becoming difficult when the pressures of Kaylee’s family legacy and perfect life start to feel less like a plan and more like a prison…and amid warm California nights and stolen laughs, Kaylee feels herself falling for Dean for the same reasons and some new ones. With their trip coming to an end, Kaylee has to make the complicated choice between doing what’s expected and taking a (second) chance on love.

Thoughts
For me, the most compelling aspect of our main character Kaylee is that she is not into commitment and long-term relationships. She works through the story to find a sort of root cause that leads to that, but I think it’s fairly unusual to have an MC who is so straight up uninterested and even afraid of that. I can only think of one other book like that: Just Listen by Sarah Dessen, which I loved intensely when I was younger.
