The lights of Prague

As the streets of Prague are overrun by creatures of the night, the city's only hope lies in the unknown lamplighters--secret elite monster hunters whose light staves off the darkness. Domek leads a life teeming with encounters with the worst kind of evil, but finds solace in the company of Lady Ora--a widow with secrets of her own. When Domek stumbles across the sentient essence of a will-o'-the-wisp, he finds himself wielding the stubborn power. After discovering a conspiracy that could unleash terror on the daylight world, Domek must race against those who aim to twist the science for their own dangerous gain.
