The last time Jess saw her father, she was a boy named Jeremy. Now she’s a high school graduate, soon to be on her way to art school. But first, Jess has some unfinished business with her dad. So she’s driving halfway across the country to his wedding. He happens to be marrying her mom’s ex-best friend. It’s not like Jess wasn’t invited; she was. She just told them she wasn’t coming. Surprise!

Luckily, Jess isn’t making this trip alone. Her best friend, Christophe—nicknamed Chunk—is joining her. Chunk has always been there for Jess, and he’s been especially supportive of her transition, which has recently been jump-started with hormone therapy.

Along the way from California to Chicago, Jess and Chunk will visit roadside attractions, make a new friend or two, and learn a few things about themselves—and each other—that call their true feelings about their relationship into question.
