Two women will do whatever it takes to protect their own – no matter the cost to anyone else. Cerys leaves her life behind in a fiery wreck. Lily slips away from hers early one morning, silent as a shadow. Both are mothers. And both are desperate. When the two women are thrown into each other's paths, they strike a tentative bond. Cerys is a mother with no children to care for anymore, and Lily is doing all she can to take care of a four-year-old on her own. But each keep secrets from the beginning—the scars, the loneliness, and, most importantly, who they actually are. They need to work together to survive, but how can they trust each other? Because everybody knows: the longer a secret is kept, the worse its consequences will be when the truth comes out. As the past catches up with them in the form of a deranged father with a shotgun, Lily especially finds herself backed into a corner. But mothers will do what they must to protect their children, no matter who else gets hurt along the way. A deeply emotional and complex thriller that explores motherhood, love and the desperate need to protect it... at any cost.
