Chris Flood - a married father of two with plummeting self-esteem and questionable guitar skills - suddenly finds himself in the depths of polyamory after years of a near-sexless marriage. His wife, Sarah - a lover of the arts, avid quoter of Rumi, and always oozing confidence - wants to rediscover her sexuality after years of deadening domesticity.

Their new life of polyamory features late nights, love affairs and rotating childcare duties. While Sarah enjoys flings with handsome men, Chris, much to his astonishment, falls for a polydactylous actor and musician, Biddy.

Then there's Zac Batista. When Chris and Sarah welcome the Uruguayan child prodigy and successful twenty-two-year-old into their lives they gratefully hand over school pick-up and babysitting duties. But as tensions grow between family and lovers, Chris begins to wonder if it's just jealousy, or something more sinister brewing...

A searing and utterly engrossing debut, Poly is a raw, hilarious, and moving portrait of contemporary relationships in all their diversity, and an intimate exploration of the fragility of love and identity.
