The Last Bookstore on Earth by Lily Braun-Arnold

The world is about to end. Again. Ever since the first Storm wreaked havoc on civilization as we know it, seventeen-year-old Liz Flannery has been holed up in an abandoned bookstore in suburban New Jersey where she used to work, trading books for supplies with the few remaining survivors. It's the one place left that feels safe to her. Until she learns that another earth-shattering Storm is coming...and everything changes.

Enter Maeve, a prickly and potentially dangerous out-of-towner who breaks into the bookstore looking for shelter one night. Though the two girls are immediately at odds, Maeve has what Liz needs--the skills to repair the dilapidated store before the next climate disaster strikes--and Liz reluctantly agrees to let her stay.

As the girls grow closer and undeniable feelings spring up between them, they realize that they face greater threats than the impending Storm. And when Maeve's secrets and Liz's inner demons come back to haunt them both, they find themselves fighting for their lives as their world crumbles around them.
