Secrets of the Sealed Forest — J.T. Tenera

It's the last day of school before summer break begins and lifelong friends Joseph Erift and Eric Castis expect to do the same thing they've done every summer; hang around the neighborhood and wait for something interesting to happen. But upon returning home, Joseph receives a letter in the mail beckoning him to embark on a mysterious quest that promises adventure and life-changing revelations.
    But little do Joseph and Eric know that their journey will lead them deep into a hidden world of arcane knowledge. Their lives are thrown into turmoil as they struggle to stop an evil entity from seeking vengeance upon his enemies. With the help of a strange old professor and an assortment of odd characters, they must fight to understand the secrets of the ancient force known as Magic, and to end the chaos that threatens to overtake the land.
