A perfect summer read full of bonfires, boats, and lazy swims, this decade-spanning love triangle novel explores the intensity of desire and loss. Jonas and Elle have known each other for years, both wondering what might have been if not for a tragedy in their past that upended their lives and potential romance.

Conversations with Friends offers a sharp, insightful look at female friendship and the transition into adulthood.

Naoise Dolan has much in common with Sally Rooney: They’re both Irish, they both write beautifully about the experience of being in one’s 20s, and Dolan’s debut novel was excerpted in the literary magazine Rooney edited in 2020. They also share an uncanny ability to excavate class, love, and the interior lives of their characters. In Exciting Times, Dolan tells the story of Ava, a somewhat detached 21-year-old who leaves Ireland to teach English in Hong Kong, where she falls for a posh English banker named Julian. Soon, however, her affections turn toward Edith, a lawyer, who starts to break through Ava’s cynical exterior.
