My Sister is literally a Demon

Karma and Angel are as opposite as a pair of identical twins could possibly be. Karma thrives on chaos while Angel can't stop running from it. Karma breaks rules constantly, and Angel is constantly struggling to stand up for herself. Adopted together in secret at birth, both girls had no idea where they came from but Karma especially always felt like she didn't belong. On one hot blustery day the pair make a discovery they never expected: their birth parents are not of this world. The result of a secret love affair between an angel and a demon both girls received the best and worst from their parents. Can the twins navigate the new world they've been thrust into and avoid falling into the same traps as their parents?
Only time will tell.
