Beyond the Shadows — Jean Van Hamme

Taken aback by Aaricia's disappearance, Thorgal is only a shadow of his former self. Eaten away with remorse, the young Shania accompanies him and protects him, hoping to find his pardon. Approached by two strangers, Worgan and Galathorn, they discover that Aaricia is still alive but held captive in the court of Brek Zarith. Ready to do anything to keep himself in power, the illegitimate master of this kingdom, Sharder, uses and abuses his evil powers. Despite all this, Thorgal will try, alone, to penetrate the impregnable fortress of Brek Zarith to save his wife and his son, Jolan.
