A Gladiator's Oath - Roman Hearts, #1

She will fight for her freedom. He will fight for her life. Mila might be slaveborn, but she has no intention of remaining a slave. Impatient for her freedom, the nineteen-year-old takes matters into her own hands. Armed with the combat skills her half-brother taught her, Mila ignores the pleas of her family and takes to the arena. She is prepared to do whatever is necessary, prepared for anything-except Remus Latinius.
Raised inside the greatest gladiator school in Rome, Remus fought hard for his freedom. He earned it the only way he knew how-in the arena. Now he is content training others to do the fighting-or so he thought. Something changes the night he meets a slave girl desperate to prove herself. He should walk away, but the gods have other plans. This is the first book in the historical action romance series Roman Hearts.
