The book follows adventures of Ash and Tor in an Earth-like world. Ash is a demon who was turned into human to learn how to be one and hopefully correct his own mistakes that resulted in a disaster for this particular universe.
Tor was given to Ash by a higher being, a "Mother" to all, to guide and help him through the process.
As much as I liked this story, the writing was not all that solid, though not bad either. There were extra characters that felt more like ghosts, rather a solid presence. Loved the plot. Will definitely read book 2 if ever comes out :)
