Isabella is following in Madre's footsteps and learning to be a healer. At the same time, she wants nothing more than a grand adventure before a husband is chosen for her. Miranda, Isabella’s best friend, is an escaped slave from the Carolina Colony with dark secrets she doesn’t want to share. But then the British invade St. Augustine, the Spanish capital of the New World, and before Isabella and Miranda can reach the fort, the drawbridge is closed. Isabella begins a daring campaign. She knows she can’t stop the British, but maybe she can slow them down until Padre returns with Spanish reinforcements. The missions become more dangerous and Miranda is captured by her former master. Can Isabella overcome her greatest fear and save Miranda, or will Miranda be forced back into slavery, while Isabella’s friends and family inside the fort, are slaughtered by the British?
