Midnight Princess by Cam Johns

After the untimely death of her grandparents, Cynthia was propelled into becoming a guardian to her younger half-sisters, Penelope and Charmaine. As they all lived under the tyrannical rule of their drunken mother, she constantly felt that this wasn’t the life that she was meant to lead. She dreamed of one day her mother becoming sober enough for her to remember that she once loved her children. Unfortunately, that day would never come, and her heart would harden with each cruel comment from her mother.
It wasn’t until her freshman year in college that she would find someone who did love her, as she deserved. Who would liquefy her hardened heart, to find the giving soul that has been hiding from her mother’s tirades. It was then that Cynthia would investigate her mother’s past, to find answers to who her mother has become. The answers that would come in the dead of night. Midnight Princess.
