Radiant Sin by Katee Robert (Paperback)

Cassandra Gataki knows better than to trust the ruling powers of Olympus. As a member of a disgraced house, she has already seen how quickly favour can vanish and how dangerous the city’s politics can become. Her only goal now is to protect her sister and eventually leave Olympus behind for good.

Apollo holds one of the most influential roles in the city. As the official spymaster, he gathers secrets that keep Olympus stable, even when powerful figures attempt to shift the balance. When a new and suspicious power player hosts an exclusive week-long gathering, Apollo needs someone he can trust to attend with him.

Cassandra reluctantly agrees to act as his partner at the event, but only on one condition. Once the mission ends and Apollo gains the information he needs, she and her sister must be allowed to leave Olympus permanently.

As the gathering unfolds, their carefully planned cover begins to blur with real emotions. At the same time, dangerous secrets begin to surface, revealing threats that could destabilise the entire city. What started as a simple undercover arrangement soon places both Cassandra and Apollo in the centre of a growing crisis.
