Physics genius Bethany Raven must find her way back to her own reality with the help of her annoyingly attractive nemesis, in this warm, funny multiverse rom-com, for fans of IMPOSSIBLE by Sarah Lotz and THE HUSBANDS by Holly Gramazio.

………

Waking after a career-defining breakthrough, physics genius Bethany Raven expects to find her multiverse theorem written in the notebook by her bed. Instead the pages are blank … and her new flip-flops are white rather than the beige she remembers buying with her sister, Cesca.

At first she shrugs it off, but then certified lazy-girl Cesca calls from the gym at 7 a.m. and Bethany can’t deny something is seriously wrong. She’s skipping through alternate universes trying on other Bethanys’ lives, other Bethanys’ increasingly diverging lives. And with each skip her relationship with Cesca becomes more and more distant.

Desperate to find a way home to her own world and her own Cesca, she’s forced to seek out the only person who might be able to help. Shame he’s her bitter rival – the cocky-as-all-hell darling of the physics world, Tyler Adams. But when Tyler turns out to be very different to the man she thought she hated, Bethany discovers that working with him to get back to her reality might not be all bad …
