Isabella Tártago is a woman in crisis.

It is nine months since she began a relationship with her roommate, Nicola. And things were going steady ? they're hosting a party to celebrate the looming Mars landing. But Nicola has never told Izzy "I love you" sober, and Izzy is questioning why they're still a couple, and if those nine months have been wasted.

But what if it never had to be that way?

Izzy has a condition ? an ability to leap into her parallel selves. But will this let her escape heartbreak, or only defer her pain?
