Declan and Sinead Boyle are pillars of society - born into prosperous families, educated at Dublin's finest schools, dwellers in a fine house in a leafy suburb. So why are they in so much trouble?

Mount Merrion, the dazzling debut novel by Justin Quinn, tells the story of the Boyles from Declan and Sinéad's first meeting, in the late fifties, through decades of success, failure and tragedy. Set against the brilliantly realized backdrop of a changing Ireland, it is a page-turning drama, a biting satire and a lovingly detailed portrait of a marriage and a family.
