Leona's Cage (Zodiac Assassins Book 4)

Thirteen Zodiac Assassins
Forged in the Darkness of the InBetween,
Ruled by the Shadow Side of their Stars,
The Only Hope for the Light of Humanity.
What Would You Sacrifice For Your Child?
Hell is sentient.
After escaping Hades, Zodiac Assassin Leona has entered Hell and found the Key, one of the two souls needed to unlock the Master of the Dark's cage. But to get to the cage, she has to survive the trip that Hell demands she make.
Hell is rage. Hell is violence. Hell is treachery.
Three circles; three visions of her damnation if she doesn't change; three efforts to destroy her. The infernal world torments her, but nothing will stop her from reaching the cage.
Hell is cruel.
The losses she has had to endure to free the Master have been excruciating, but now she must choose: unimaginable power as his apprentice or a cage of her own making - for the sake of life and love and hope.
