It’s the start of junior year, and Sammy Walker is excited to dive in with her three best friends—Noah, Jessie, and Ellie—even as she quietly wrestles with the fact that Noah and Ellie are now dating. The four of them have been inseparable since kindergarten. She’s known Noah the longest; when they were five, he told her he’d marry her someday. Now, Sammy’s convinced herself that Noah and Ellie are perfect together. Any feelings she had? Tucked away in the book she’s been secretly writing since fifth grade. A book no one will ever read.

Until everyone does.

Somehow the book makes it out of her Google drive onto every phone on the school campus. Overnight, Sammy goes from invisible to infamous. Having lived her whole life cocooned and in the shadows, and deliberately so, with this turn of events Sammy finds herself isolated from everything she has known her entire life. Particularly Noah. 

In a desperate attempt to take the spotlight off her and convince the world and her friends that she is not in love with Noah, Sammy strikes up an unlikely friendship with Theo Ellington. Mysterious. Elusive. British. The boy who became a campus legend even after moving back to London at the end of freshman year, only to return junior year with more fanfare than ever.  Someone Sammy has quietly and somewhat resentfully watched over the years from the shadows. He’s the last person someone like Sammy Walker would confide in, but her circumstances leave her with little choice.

What starts out as an implausible association, soon turns into an awkward acquaintance. One that benefits both. Theo helps Sammy navigate the quagmire of a high school scandal with his star power, and together, they begin investigating who leaked her book. In turn Sammy’s constant presence next to Theo Ellington helps him thwart unwanted attention from other girls. They find themselves more and more in each other’s company. Shared classes turn into shared lunches. Drama club rehearsals lead to inside jokes. Car rides blur into long conversations. Rumors swirl. Soon the high school chatter shifts from the debacle of Sammy’s leaked book to speculations of the two being an item. Theo Ellington seems to be unbothered by these speculations, but Sammy is caught between a rock and a hard place. Noah and Theo: the one she’s always loved, and the one who's actually here.
