El Secreto del Dragón (El Sendero del Guardabosques, 17)

A devastating war is brewing, and the Snow Panthers have an impossible mission: this time their objective is not to track enemies in the forests, but to prevent the kingdom from falling into a deadly trap orchestrated from the shadows. Thousands of leagues away, Lasgol will fight alone in a suicidal battle. With Camu and Ona, he will cross half a continent, to the fearsome southern deserts, in search of objects of power that the immortal dragon himself covets for his dark plans.
