'Wonderfully authentic, electrifying' Clare Chambers

Two couples. Twenty years. One unforgettable story.

Dylan, Stevie and Ben have been inseparable since their days at Trinity, when life pulsed with possibility. A single glance can still summon their younger selves: dancing beneath flashing lights, salt on their skin after swims in Dublin Bay.

Two decades later, their dreams have faltered. Dylan, once a rugby star, is stranded on the sofa, tended by his wife, Rachel. Across town, in their new build, Stevie and Ben's relationship has settled into an airless routine. Then, after countless auditions, Ben lands a role in Pinter's Betrayal.

As rehearsals unfold, the play's shifting loyalties seep into reality, stirring old jealousies and awakening forbidden longings, as each must confront how far they are willing to go in pursuit of desire.

Wry, sexy and deftly observed, Little Vanities is a novel about the perilous thrill of stepping outside the roles we've been given-and the distance between the lives we imagined and the ones we find ourselves living.
