I need a title!!!!!!!!!

I need help with a titre for my book that will probably be posté on here eventually!! Basically it's a medieval fantaisie story about 6 kingdoms (plus a 7th that was destroyed). There's a girl named Kayla who's a princess in one of the kingdoms, and her and her twin sister Danna are cursed. Danna (who's not a very big part of the novel) is forced to see the past and future of anyone she meets and as a result, she shut herself away from all humanity. Kayla's power is that anything she stares at for a certain period of time lights on fire. Kayla hates being a princess and also, the kings are really tyrannical as a result of a war, so she runs away and joins a rebel team, pretending to be a peasant girl named Finnigan. At the same time, it also tells the story of another girl named Ash who lives in the destroyed kingdom; she Lost her memory and is trying to figure out why her kingdom was destroyed and find other people there. Eventually the two get united, and plus stuff happens that I'm not sure of yet.
Does this idea sound good, and do toi have any titre suggestions?
