Tracing the intertwined lives of two couples from their Trinity College years to the reckonings of midlife, Little Vanities is a radiant story of love, desire and fidelity, and the fragile scripts we live by

Dylan, Stevie and Ben have been inseparable since their days at Trinity, when everything seemed possible. A glance between them can still conjure their younger selves: dancing beneath pulsing lights, the sharp taste of salt after swims in Dublin Bay.

Two decades on, life feels smaller. Dylan, once a rugby star, is stranded on the sofa, cared for by his wife Rachel. Across town, Stevie and Ben's relationship has settled into weary routine. Then, after countless auditions, Ben lands a role in Pinter's Betrayal. As rehearsals unfold, the play's shifting allegiances seep into reality, reviving old jealousies and awakening sudden longings, as each must reckon with how far they're willing to go in pursuit of desire.

Wry, sexy and deftly observed, Little Vanities is a novel about the dangerous thrill of stepping outside the roles we've been given - and the distance between the lives we imagine and the ones we live.
