The Epiphany of an Explorer (Brothers of the Aristocracy book 3)

When archeologist Dr. Stewart Jones, a duke, goes missing and is feared dead while searching for an important Greek artifact, explorer Harold Tennison, Earl of Everly, is pressed into service to find him. He's already scheduled an expedition to the Cyclades to search for rare birds and flowers, so he sets off for the Aegean to begin his quest.

Born to a Mykonian mother and a British duke, Lady Estelle isn’t particularly comfortable in either world. With her father’s recent disappearance and no prospects for marriage, Stella may end up stranded on Mykonos. She spends her days assisting her uncle in his hunt for Greek treasures he can sell to visiting Europeans. At night, she remembers the bespectacled earl who nearly broke her foot during a waltz back in London. When Harry arrives on Mykonos to begin his hunt for the duke and to resume his own research, he’ll have to learn far more about mythology, antiquities, and Greek goddesses than he bargained for. The search may be worth it, though, especially if he ends up with his very own Aphrodite.
