One thing that really hooked me was the vast possiblity ingerent in the magic structure that is lacking in most books. Tom seems to be in an adventure of discovery and invention. As a lovers of crafts and knowledge, this kinds of adventure is what I root for and desire most. The similar adventure of discovery that Einstien, Tesla, Newton, Edison, etc. have ventured.
Tom had already tinkered with magic and had some success already with stealing mana from a God, which it seems to have not been possible, or so thought. He might gather similar infamy as Ramses and his Time Warriors.
I really looked forward in what Tom would do with his magic abilities and the discovery he will find therein.
