Libby Graham's twenty-year marriage was supposed to be load-bearing. After three miscarriages, years of IVF, and one brutal discovery in a cloakroom, it finally collapses. With her husband's affair exposed and their last frozen embryo signed away, Libby is left with a cracked house, a hollowed-out body, and a life she no longer recognises. What she still has is her work. As an architect who specialises in retrofits, she knows how to coax beauty and strength from damaged buildings. She just can't seem to do the same for herself. Then, in a London pub on the worst week of her life, she meets Zack Harper — a quietly dominant structural engineer with a steady gaze and two unbreakable rules: never build on rotten foundations, and never play with someone who can't say no. A shared project on Newcastle's Quayside draws them together. As the warehouses they restore are stripped back, braced, and brought to new life, Libby is slowly drawn into Zack's world of negotiated power and rope-soft restraint. With meticulous consent and a patience she's never known, he offers her a place to hand over the weight for a while — without breaking. But retrofitting isn't about pretending the cracks were never there. It's about exposing what failed, cutting out what's rotten, and choosing — again and again — what's worth salvaging. To claim the fiercely tender love Zack offers, Libby must do the riskiest thing she's ever done: believe she is not broken, that her body is more than a graveyard of failed hopes, and that she is allowed to want — sex, rope, safety, and a future that looks nothing like the one she planned at twenty-three. A raw, emotionally rich romance about grief, betrayal, healing, and chosen surrender. For readers who crave mature heroines, trauma-aware kink, and love stories built on honesty, consent, and more than one kind of strength.
