Banished — Sandra Schwab

A proud warrior.
A brave woman.
A forbidden love that is tested by the intrigues of ancient Rome and the hostilities at the northernmost edge of the empire.

Centurion Marcus Florius Corvus has a splendid career in the legions ahead of him. Yet a visit to Rome and a chance encounter with an old friend change his whole life: He falls in love with one of his friend's pleasure slaves and becomes entrapped in an evil scheme designed to destroy him. And yet -- he cannot help risking everything for Lia, the woman he has given his heart to, even if it means he will be banished to one of the most dangerous places in the Roman Empire: the northern frontier of Britannia.
