Growing up across the street from each other, Scott and Cath have been best friends their entire lives. Cath would help Scott with his English homework, he would make her mix tapes (it's the 80's after all), and any fight they had would be forgotten over TV and cookies. But now they've graduated high school and Cath is off to college while Scott is at home pursuing his musical dreams. During their first year apart, Scott and Cath's letters help them understand heartache, annoying roommates, family drama and the pressure to figure out what to do with the rest of their lives. And through it all, they realize that the only person they want to turn to is each other. But does that mean they should be more than friends? The only thing that's clear is that change is an inescapable part of growing up. And the friends who help us navigate it share an unshakable bond.
