I read a book about 7-8 years ago about two sisters. I think it was (kind of) a young adult's book, but I really want to finish the series, so I'm asking for help finding the book I read. Okay, these are the details I remember:
- Both sisters are princesses, one is supposed to protect the other
- One of the princesses has a winged lion (I can't remember the name of the lion)
- When the princess supposed to protect the other princess is scared, the lion says something about "flying high and seeing the stars"? Or something like that.
- They meet again after some time because of some important thing
- Apparently, the two have to convince a superbeing or something to keep the continent safe.
With this information, can someone help me find what I'm looking for?
