Breathe, and Release — Katherine Hayton

Elisabet wakes with amnesia. The care offered to her by a husband she doesn't remember descends within weeks into aggression and violence. Lillian lies hogtied in an underground cell. Forget about escape; unless she can manage the necessities of life she'll be dead within days. Kristen lost her house, her friends, and her confidence when her parents separated. Now her injured stepmother has moved back in. Has she lost her memory, or lost her mind? Will the secrets hidden in Elisabet's locked memory be enough to set them all free?
