Other Worlds

Depressed FL used to be a princess but is now ridiculed with a cold uncaring husband. She takes her life to end up in her husband's body.

FL has potential and is a half blood of a family but wasn't recognised by the grandfather until too late. She watches the house go to ruins but she comes back to life as a seven year old where she may be able to save her dad.
