The Lost Guitar
William Sawyer

It allows for guitarists to play and learn chords in a fun manner with the adventures of you and Rapu going into a realm of darkness to restore the lost kingdom. There are spirits and trolls and all sorts. Also, the student gets to choose a path by which chord they play as well. It also allows for students to work together and help each other learn chords.
