Stolen Magic

Wyatt D'Artagnan Junior has one goal in life: to rescue his favorite Aunt from the clutches of some extraterrestrial being that kidnapped her in a cloud of golden smoke. Little does he know, of course, that the being he's hunting is a Greater Deity, and the god of Magic itself, a Primordial Deity that predates most known life and controls the very Weave of Magic in the entire known multiverse.

His quest gets quite a bit easier, suddenly, when he learns that his aunt, the celebrated matriarch of their family and the one who had built their small company in such a way as to provide for them all, has not only been reincarnated, but become something of a demagogue in the world she's been taken to; now, even beyond the grave, she's given him the opportunity to go give what-for to the deity who took her, and he's bound and determined to carry out his crazy little plan!!!

One catch: if you want to use Magic to fight a God of Magic, you have to be pretty damned good at it... and you have to be able to cast it without Mana. Just slight bumps in the road for someone as smart as Wyatt Junior; of course, that's what he'd say if he was asked, even if it's totall bullsh-
