Kris has grown up in the region of Argon haunted by a recurring dream of a day he can barely remember but is lucky to have survived. When his mother Helena wakes him in a panic to report that his father Kurtis, Argon's legendary guardian and greatest dragon slayer, has gone missing, Kris is thrust into real danger. The timing could not be worse: this is the month when the dragons sealed inside Argon's four manmade caverns stir from their long sleep, flooding the land with monsters drawn to their power. Armed with his spear and driven by love for his father, Kris sets out on a journey that will force him to confront the truth about that dream and discover what he is truly capable of.
