fake dating • forbidden romance • friends to lovers • Greek mythology retelling • fake relationship

Cassandra Gataki knows better than to trust Olympus's powerful Thirteen. After the fall of her family, she's learned exactly what happens when you put your faith in the wrong people. So when Apollo asks her to pose as his plus-one at a week-long party hosted by a dangerous new power player, she agrees on one condition: once the mission is over, she and her sister get the freedom they've been fighting for.

Apollo may be Olympus's golden god and master of secrets, but Cassandra is the one person he trusts completely. What begins as a carefully staged fake relationship quickly develops into something much more real, forcing them both to confront a threat that could destroy not only their carefully guarded hearts, but Olympus itself.

The Vibe

Cassandra is a sharp, guarded heroine who has learned to survive after her family lost everything. Determined to protect her sister and secure their freedom, she agrees to play Apollo's perfect partner despite knowing that getting close to one of Olympus's most powerful gods could come with a dangerous price.

Apollo is Olympus's charismatic spymaster, a golden god known for his ability to inspire loyalty and uncover secrets. He trusts Cassandra more than anyone, but pretending to be lovers makes it increasingly difficult to ignore the attraction simmering beneath their friendship.

With fake dating, forbidden chemistry, political intrigue, secret identities, and scorching tension, Radiant Sin gives the myth of Apollo and Cassandra a dark, modern-romance makeover. As their undercover mission spirals into real danger, Cassandra and Apollo must decide how much they are willing to risk for each other and for the future of Olympus.
