Mara and Jo have been inseparable since they met at 14, with Mara being the reliable one and Jo often finding herself in turmoil. Both lead unstable lives, juggling uncertain jobs and unfulfilling relationships, while writing remains a side pursuit, as is common in Brooklyn. Their friendship, or rather its dynamic, is the only constant amidst their daily routines and conversations: Mara’s phone will ring with Jo needing assistance, prompting Mara to drop everything, only for Jo’s mind to have wandered by the time she arrives. The narrative gently progresses, highlighting different instances of this recurring pattern, with Jo’s struggles intensifying and Mara’s frustration mounting. As time goes on, they experience new jobs, relationships, encounters with drugs, emotional moments, and fresh beginnings, including a pregnancy and eventually a little girl, all of which gradually test the strength of Jo and Mara’s friendship.
