The work tells the story of Alice Kelleher, an Irish novelist, and her best friend Eileen Lydon, an editor at a
literary magazine. In alternating chapters are descriptions of their lives and emails they send each other. The two other important characters are Kelleher's new lover Felix Brady, who works at a warehouse, and Lydon's friend Simon Costigan, who works as a policy adviser. In
The Guardian, Anthony Cummins describes the novel's structure as a "love quadrangle" between Kelleher and Brady, on the one hand; and Lydon and Costigan, on the other.
Beautiful Worlds themes include romance, friendship,
precarity, and
social class. The title comes from a poem by
Friedrich Schiller which
Franz Schubert set to music in 1819. The novel includes substantial
epistolary elements, such as emails between Kelleher and Lydon. == Publication and release ==
