Demon Holiday

Torval, Demon Third Class, Layer Four Hundred Twelve of the Eighth Circle of Hell, has been walking his route
torturing sinners for as long as he can remember. It's the only job he's ever had or wanted, and he's never had any reason to question why he does what he does. Everything's perfect in his little corner of the universe, until one day he witnesses something so shocking, so impossible, it shakes him to the core. When his job performance begins to suffer, his demonic overseer sends Torval on his first vacation in all his centuries of existence--a holiday on Earth, the proving ground for souls!
