Book one of two! Lilith Snape was going to make a promise after fifth year. She just hoped that crossing her fingers behind her back would work to bend her words to him. To him, the boy who she had hated. The boy that she would do anything for. The boy that she never wanted to actually find good in. Was there good to find? He was Voldemort's son. But Lilith never knew that finding a little good in a boy would change the way she felt about it. She never knew that she would make a promise that would break his heart when he found out. She never knew that, with the war starting up, she would change more. She always said that the things people didn't know wouldn't hurt them. But, in the end, would she really believe that? Mattheo Riddle x OC This is your warning! this story contains themes such as: -smoking -drinking -suicide(ish) -drugs -sex -cussing And a fucking liar.
