The Journal of Irene Summerset - Fantasy Unleashed: Akiyama Quest, #1

Darci and Benni are about to embark on an adventure of a lifetime when they find themselves investigating the mysterious disappearance of Professor Summerset.   Darci and Benni's summer program experience is about to teach them more than they had bargained for when a professor at the university mysteriously disappears.  Upon finding Professor Summerset's journal, they are thrust into a world beyond anything they could have imagined - an eighth continent known as Akiyama.
 However, Darcy and Benni's search for the missing professor will prove harder than they could have ever imagined.  In this secret land, wonders and dangers alike will meet them at every turn and they have only the professor's journal to aid them.   In a society that calls the rest of the world forbidden, the friends will need to trust each other even more as they navigate through this place of magic with talking animals, wizards, magical horses, a mysterious ruler and a dangerous organization.
 They must rely on each other, find the professor and hope that the journal will be enough to lead them back home.
