The Vampire Flame oleh T.L. Cerepaka

Save the Flame.

When my best friend Jane is kidnapped by a crazy sorcerer, I have to team up with my vampire friend Lucius to save her. Not too difficult.

But what starts out as a simple rescue mission becomes much deeper when it turns out that this same crazy sorcerer is trying to find the fire which is the source of all magical power in the world. And not only is he trying to find it, he's also trying to extinguish it.

Failing to save Jane won't just result in her death. It will also result in the destruction of magic itself.
