The Sky Palace

Raiyn sees things. Things that she's not supposed to see. Dragons, faeries and towering castles. At first, she thought she was completely delusional fourteen year old, but that quickly proves to be wrong. She meets Theodore, a boy that can see too. Her parents think she's mad. But Raiyn is perfectly sane; if only the outside world could see what she sees. Follow Raiyn and Theo, as they embark on an incredible journey into the Sky Palace, the place of the living and lost souls of heroes, while their loved ones are stuck in time.

I believe the cover was someone's Devianart, but I had edited it a whole lot. The background does not belong to me, and if it's yours, I will gladly take it down.
