Firsts Are Always Messy by Jessi Hansen

Jenny Kearns and Matt Thompson are best friends and next door neighbors who share everything, even a weird obsession with Pokémon. When a bet blurs the lines between friendship and love, things get complicated and messy. Especially after Matt breaks their pact to go to Prom together and asks Audra Jenkins to be his date instead. Jenny isn’t sure how to pick up the broken pieces of her heart until Matt’s older brother, Kyle, offers to teach her how to drive. With Matt out of the way, Jenny finds herself drawn to the brooding, mysterious boy next door. And she soon discovers the pangs of unrequited love can’t compare to the real thing.
