A student navigates troubled relationships at age 19 and 25, as he comes to terms with mental health difficulties

“The best way to make sense of life,” Derek Owusu believes, “is to write about it.” His semi-autobiographical debut, That Reminds Me, was an attempt to understand how he came to be diagnosed with borderline personality disorder: a condition marked, among other things, by intense emotions, self-destructive impulses, fear of abandonment, black-and-white thinking, and an unstable sense of self. The novel, written in an elliptical and densely poetic style, offered an illuminating, if harrowing, account of alienation, addiction and self-harm, through the story of K, an alter ego whose early childhood, like Owusu’s, was spent in foster care. It won Owusu the Desmond Elliott prize in 2020, and announced him as an idiosyncratic talent; in 2023, he was named one of Granta’s Best of Young British Novelists.

Owusu now turns again to the subject of BPD, this time exploring the complexities and contradictions of living with the condition. His narrator, Marcus, is 25 when the book opens. An English literature student of Ghanaian heritage, he is at a speed dating event when he meets San. San is strikingly beautiful, and she grabs his attention right away: “So, yes, I was in love again, losing balance, stumbling towards an earlier phase of my life.”
