What If It's Us by Becky Albertalli and Adam Silvera

Meet Arthur and Ben.

Arthur is only in New York for the summer, but if Broadway has taught him anything, it's that the universe can deliver a show-stopping romance when you least expect it.

Ben thinks the universe needs to mind its own business. If it had his back, he wouldn't be carrying a box of his ex boyfriend's things.

But after a chance meeting at the post office, the boys leave wondering what exactly the universe does have in store for them.

Excellent condition.
