Daughter of Kronos, The Forgotten Girl 
PSA: just . . . don't read this. The grammar is awful, the characterisation is awful, so many things about this are awful. You have been warned
Rose never had a normal life, after all she was a daughter of Kronos and didn't get on with the Olympians very well. When Kronos starts to get stronger, her powers grow stronger and stronger, until she is unable to control them without the help of her brothers. She goes to camp half-blood and meets the lightning thief. Will she be able to stop her brothers from starting World War III?
