Jack Cross just wanted to play a game. And now he is fighting for his own life! When a mysterious hacker gains control of the Hundred Kingdoms, Jack finds himself trapped inside a VR fantasy world, along with millions of other players. Only his situation is even more dangerous than the rest. After all, his refuge was the very tower that the terrorists made their base. Jack is the only free player within these walls. To make matters worse, in the real world his body is suffocating from the heat in a stuffy room, with no hope of salvation. Considering that Jack started the game at a low level in the scavenger class, his chances of breaking through are close to zero. However, he tries to do the impossible: Jack creates weapons, equipment and traps in an alliance with a deadly dungeon master and artificial intelligence (whom he does not fully trust) and enters a battle against time to save not only himself, but also millions of other players - hostages. “On the Hook” is a peculiar mix of the atmosphere of World of Warcraft and Die Hard, using the bright mechanics of the LitRPG genre with a focus on crafting. The reader will find here detailed descriptions of game items and spells, tables of character properties and sets of parameters for classes.
