No Such Thing as Monday by Siân Hughes

Steffie spends her days working in a dry-cleaner's, trying to scrub the world clean one garment at a time. But no matter how spotless the clothes, she can't rid herself of the guilt and grime she feels inside. Haunted by what happened to her sister when they were children, large fragments of which she can't fully remember, Steffie is stuck in a loop of self-destruction, defiance, and shame. When her violent, bullying father dies suddenly, it sparks a reckoning that cracks open her past. What follows is an unexpectedly redemptive journey of a woman trying to piece herself together in a world that failed to make space for her.
