From the bars of New York's East Village to the neon forest of Tokyo's underworld, from the hidden waterfalls of Hawaii to the slums of Mexico City, this novel is a journey that spans continents and mental states.

Driven ever onwards by a savage love, Keelin is searching for her sister, Aisling, who disappeared from her home in Ireland one summer without warning. Her family is devastated, haunted by the loss, with only exotic postcards as hints to her whereabouts. But the postcards have long since dried up and Keelin is determined to track her sister down. A schoolteacher, who has always lived with her mother, Keelin has led a sheltered life in Ireland, but as she visits the places where Aisling has been and encounters the trial of friends and lovers that her sister has left behind, she finds herself being sucked into the dark, erotic world that Aisling inhabits.

Things begin to go awry, and the search becomes a ruthless hunt when family secrets are revealed and betrayals imminent. In relentless pursuit, Keelin is forced to question her own identity and put a name to the affliction that continues to curse her family. A brilliantly wild, fast-paced odyssey, this novel consolidates the author's reputation as one of Ireland's most exceptional young writers.
