Courageous Heart (The Von Wolfenberg Dynasty Book 2)

Lute von Wolfenberg is the carefree middle son of the family with no responsibilities, but no prospects either. Obliged to fight in the army of the Holy Roman Emperor in a foreign war, he struggles to hold on to his sense of humor and optimism amid the betrayals and atrocities of the campaign. He finds himself drawn to Francesca di Cammarata, niece of the Emperor's arch enemy, Roger of Sicily.
She is an arrogant princess brought up in the lap of luxury whose duty lies in thwarting the imperial troops, but she cannot deny her feelings for Lute.
The conflict will test their loyalty to country and family.
