On a snowy morning in 1978, 18-year-old Leah Cavanagh meets Brother Matthew while on a Retreat with her girls’ school. The four days she spends at Greystones Abbey in the wilds of North Yorkshire will have a profound impact not only on her own life, but also on that of her single mother Molly, who never recovered from the murder of her fiancé in 1956. Brother Matthew and Leah start writing to each other and soon an unspoken attraction develops, shared vicariously by Molly. When Leah leaves home to study at music college, she keeps returning to Greystones Abbey. The forbidden desire between Leah and Matthew deepens on each visit, until boundaries are finally broken. Now Leah finds herself unable to break free, neither from her manipulative mother, nor her tortured monk. She knows she will have to make a choice … but how do you choose between two people who are tearing your life apart?
