Doctors, Assassins, and Other Tyrants - Katharine Campbell

In this sequel to Love, Treachery, and Other Terrors, seventeen-year-old Augustine has a near-perfect life. His mother and stepfather adore him, he is looking forward to a promising career as a knight, and he's pretty sure the doctor's daughter likes him as much as he likes her. Aside from the occasional duel with his cousin, he doesn't have any real problems. 

Until he's kidnapped by a band of highwaymen. As if tying him up and dragging him away from home wasn't bad enough, the ruffians start spouting nonsense about how he is the illegitimate son of some horrible, honorless, murdering prince named Justin. 

Augustine, of course, doesn't believe these vile rumors. By his mother's own account, her late husband was the perfect man in every imaginable way. She would never lie to him about something as important as his father... right?

In this quirky, medieval fantasy Augustine must find a way to escape his captors and uncover who he really is. It's a story of providence, heroism, and learning to embrace the truth.
