Jars of Clay (Jars of Clay #1)
Lee Strauss

Sixteen year old Helena Vibius is the daughter of a wealthy business man in the city of Carthage, North Africa in the year 199AD. She’s not granted a tutor like her two older brothers are and must be satisfied with the teachings of her father. Which she is not.
Eighteen year old Lucius is a freeman--not a slave--living and working on the Vibius compound. His biggest desire is to learn about the world and one day leave Carthage to see it. A serendipitous meeting with the master’s daughter presents an opportunity. Should he take it?
Helena agrees to secretly teach him, a rebellious gesture that surely could do no real harm--as long as they’re not caught. And she mustn’t fall for this servant boy, either.
Sometimes one does what one must not.
