Mary McConnell grew up longing for information about the mother she never knew, who died suddenly when Mary was only a baby. Her brother Sean was barely old enough to remember, and their father numbed his pain with drink. Now aged thirty-five, Mary has lived in the same house her whole life. She’s never left Belfast. She has a son, TJ, who’s about to turn eighteen, and is itching to see more of the world. One Saturday morning, TJ wakes up to find his mother gone. He doesn’t know where – or why – but he’s the only one who can help find her.
