The Greek Tycoon's Secret Heir (Harlequin Comics)

Ava fell in love with Christos, the second son of a wealthy family, while in Greece. But their happiness didn't last long. Suspected of cheating on Christos with his older brother, Stavros, Ava was chased out of Greece. So when Christos comes for her five years later, Ava can hardly believe her luck. She thinks he finally believes that her son is indeed his own, and not his brother's—but her hopes are quickly crushed. Staring at her coldly, Christos informs her that Stavros and his wife died in an accident, and he's come for Stavros's son—the family's secret heir!
