Marlowe Meadows understands a lot of things. She knows calculus isn’t universally beloved, and Python coding isn’t the ideal topic over beer pong. She also knows people were surprised when golden boy Josh asked her out, transforming her from the weird, math-obsessed girl into half of their school's couple goals. What she didn’t expect was Josh dumping her for someone more romantic, with more emotional depth.

Determined not to fail at anything, especially love, Marlowe hatches a plan when she's paired with Ashton Hayes for an English project. Ashton’s black clothing and moody eyeliner cause a systems overload in her organized mind, and the dissonant sounds of his rock band make her brain itch. But when she stumbles upon Ash's stash of love songs, Marlowe makes a desperate deal: if Ash helps her write love letters to win back Josh, she’ll create the perfect data analytics formula to make his band go viral.

As the semester heats up with heartfelt love notes, romance novels, and late nights spent with a boy who defies categorization, Marlowe begins to wonder if there’s a set solution to love. The precise calculations and algorithms that guide her life can’t seem to account for the sparks flying between her and Ash. For a girl who’s never met a problem she couldn’t solve, Marlowe might have gotten the math massively wrong. Could the key to love be less about formulas and more about following her heart? ❤️📚❤️
