A creature unlike any other is born into a haunted realm. One that must be protected…no matter the cost. Orphaned in an underground refuge, Riony struggles to keep herself and her adopted sister safe. But survival soon becomes the least of her worries when Riony takes in a creature whose very existence could be her destruction. In a land where unicorns have been hunted to extinction and dragons are the exclusive possession of the dragonlords, it’s a death sentence to be tasked as caretaker to a dragon-unicorn hybrid. She can’t leave the little one to fend for itself, but when her sister is kidnapped and rescuing her hinges on a desperate journey into the cursed overworld of the shadow dragon, she knows the impossible challenge faces her with an impossible decision. Leave the creature behind in sacrifice to save her little sister…or sacrifice her little sister for a greater good.
