Tomboy Alex Bonham has fought her male peers tooth and nail to prove herself worthy to become captain of the king's guard. When her country is invaded by Danes, she is ordered to take the king's younger son, a charming but irresponsible rake, away from the front lines for safekeeping.

Alex walks a difficult line, trying to balance her growing attraction to Prince Holden with her dedication to duty and her responsibility to keep him safe from robbers, Danes...and even himself. But when they are drawn into the struggle to defend East Anglia from occupation, both the prince and his captain must grow. Can spoiled Prince Holden evolve into a good man who could lead the kingdom—one Alex can trust with her heart?
