Lily Carson is a tech genius who's got it all figured out—except when it comes to her own love life. After too many disastrous relationships, she channels her frustrations into creating Ex-Change, a revolutionary dating app that lets users trade their exes for someone else's. It's the perfect way to leave the past behind and take a leap into a brighter romantic future. At least, that's the plan.

But when Lily's ex-boyfriend, the devastatingly charming Evan Brooks, becomes the app's most popular "trade," things spiral out of control. Evan is swapped from one disgruntled ex to another until he lands squarely in the arms of Maya Devereux—Lily's arch-nemesis and a glamorous lifestyle influenced who lives to one-up here. For Maya, snagging Evan isn't just about rekindling an old flame; it's about winning, and she's ready to flaunt their reunion all over social media.

Determined to prove her app's success and outshine Maya, Lily hatches a plan to win Evan back—if only to save her company's reputation. But just as her plan is set in motion, Ex-Change glitches spectacularly, matching users not only with their past flames but with future versions of potential partners. Suddenly, Lily is faced with multiple future Evans—one where they're happily married with kids, another where they're business partners, and even one where they're divorced but amicable.

And then comes the biggest surprise of all: Lily is matched with a future version of her best friend and business partner, Ryan—who's secretly been in love with her for years. As she navigates this hilariously chaotic twist, Lily starts to question everything she thought she knew about love, timing, and the perfect match.

In this side-splitting and heartwarming tale, The Ex-Change isn't just a tool for trading in the past—it's a journey that forces Lily to confront her deepest fears, her true desires, and the realization that the love she's been searching for might have been right in front of her all along.

Perfect for fans of clever romantic comedies with a twist, The Ex-Change is a story about the unpredictability of love, the courage to take risks, and the joy of discovering that the best things in life can't always be planned—they just have to be chosen.
