The Adventures of Mystic & Sage Omnibus

The Adventures of Mystic & Sage Omnibus is a collection of 7 cozy fantasy books, with a South African twist.
Sibling mages, Mystic and Sage travel to different gaming worlds in each of their adventures, where they have to complete each quest before they can return home.
They start out in a Medieval world, visit Victorian England in their second Steam Punk adventure, go back to the Stone Age in the third volume, deal with the Elves and Fae in number four, go to space in the fifth adventure, suffer through a Post-Apocalyptic world in the sixth volume and end up in Feudal Japan for their final, big boss fight. They gain and lose companions along the way and discover the answers to life-long questions, while learning magic and dealing with the unique challenges of each world.
