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?
