Kestra never knew what happened although the night before her father disappeared Kestra had been told to go and look for Toby Kestra's older brother who disappeared 16 years ago. He had the key to Elsalvador and without him whoever entered would forget everything from the outside world.
It's almost Kestra's 17th birthday and she has to return with her brother who had the key or everything and everyone she knew and loved would vanish. Kestra has 60 days to get the key from her brother and make it back to Elsalvador and sit on the throne.Time is ticking.
