The Devil’s Game by Roman Koidl

Michael’s curse kills those he loves—and he doesn’t even know he’s cursed.

The Vegas trip was supposed to be fun. Quality time with the girlfriend for her birthday, bright lights, drinks, and good times. But a simple game of roulette unleashes a deadly curse with an age-old secret; Michael needs to do what his ancestors never could—destroy the Devil’s chances of ruling the world.

With a beautiful demonologist at his side, hunted by a mercenary of The Thirty-Six Legions of Demons Sect named Baal, followed by private eye Joe Harris, Michael’s chances for success, are, well, zero.

Following a century-old trail of clues that lead through dangerous catacombs, a mysterious castle, and cryptic texts in ancient books, they trek across Europe searching for a way to stop the Devil from ultimate power.

And all of it is somehow intertwined with the history of roulette. Can Michael find the answers and stop the Devil before it’s too late and more get killed?
