Even though Osiris was an avid storyteller since he could talk, he only dared to commit his stories to paper after his future wife basically manhandled him to. The two of them are currently living their happily ever after in Kassel, Germany, doing so under the stern but loving surveillance of their cat.
Osiris leads an unassuming day life as a specialist accountant, but in his spare time writes fantasy, science fiction and historical fiction with gay romance themes, having a ball herding plot bunnies with his congenial wife.
