Žoldáci 2 - Slib Čarodějného krále – Salvatore R. A. (2015)

The book was well hidden. Its pages promised the power of the Sorcerous King himself. And now that it has been found, not even the fact that anyone who opens it will die can prevent people from fighting over it. Welcome to the Krevels! On the orders of dragon patrons, the human assassin Artemis Entreri and his companion, the dark elf Jarlaxl, head into the demon-infested wastelands. It doesn't take long before they find themselves right in the middle of a conflict between powerful forces that would prefer to kill them – or worse... But Entreri and Jarlaxl are not ordinary wandering mercenaries, and the ancient evil and fierce blood feuds of the wild Krevels may have met their match.
