"Her fate has sent Olympus into a state of chaos and fear.
Artemisia has a singular destiny: to overthrow her father, Zeus. Raised and protected in the Underworld, she has had twenty years to come to terms with what she must do. Except her father is relentless in his pursuit of her, willing to cross any line and sacrifice anyone. If Hades loses the trials, he will have to give up one thing of Zeus' request: Artemisia.
Orion is one of twelve champions chosen by one of the Olympians to compete in the trial of the gods. The rules are simple: survive. Chosen by Hades, he struggles to use the power gifted to him for the competition, but failure is not an option. His family is desperate, and if he survives long enough in the trials, he can secure their future. The promise of a quest for immortality for the winner has never mattered to him, only making it to the final trial where Zeus will grant him one request. At least, that was all that mattered until a pair of brown eyes.
Sia and Orion's story takes place twenty years after the epilogue of The Swindler and The Swan. While it is not necessary to have listened to Hades and Persephone's story prior to The Chaos and The Hunter, it may enrich the experience."
"When the goddess Demeter shows up to a party on Olympus in Hades' signature color, he decides to react to the slight by stealing her beloved swan.
However, as soon as they cross into the Underworld, the swan changes into a woman revealing that she is Persephone, daughter of Demeter. Eager to continue his plot to annoy Demeter, Hades agrees to help Persephone break the curse on her, but he soon finds that she is nothing like he expected. What starts as a harmless revenge scheme turns into something else entirely.
Persephone can't remember a time when she didn't spend her days as a swan and her nights as a woman. Trapped and confined to her mother's lake for her entire life, when Hades steals her she is offered a way out for the first time. While in the Underworld, she won't transform. If there re is one thing she knows, it's that she is never going back. As a new world opens up to her she finds that the god of the Underworld is nothing like she expected and he has a lot to teach her."
