It once seemed so easy to Prince Rhen, the heir to Emberfall. Cursed by a powerful enchantress to repeat the autumn of his eighteenth year over and over, he knew he could be saved if a girl fell for him. But that was before he learned that at the end of each autumn, he would turn into a vicious beast hell-bent on destruction. That was before he destroyed his castle, his family, and every last shred of hope. Nothing has ever been easy for Harper Lacy. With her father long gone, her mother dying, and her brother barely holding their family together while constantly underestimating her because of her cerebral palsy, she learned to be tough enough to survive. But when she tries to save someone else on the streets of Washington, DC, she's instead somehow sucked into Rhen's cursed world.

It's 1889. Paris is on the cusp of industry and power, and the Exposition Universelle has breathed new life into the streets and dredged up ancient secrets. Here, no one keeps tabs on dark truths better than treasure-hunter and wealthy hotelier Séverin Montagnet-Alarie. When the elite, ever-powerful Order of Babel coerces him to help them on a mission, Séverin is offered a treasure that he never imagined: his true inheritance. To hunt down the ancient artifact the Order seeks, Séverin calls upon a band of unlikely experts: An engineer with a debt to pay. A historian banished from his home. A dancer with a sinister past. And a brother in arms if not blood. Together, they will join Séverin as he explores the dark, glittering heart of Paris. What they find might change the course of history--but only if they can stay alive.

As the last child in a family of daughters, seventeen-year-old Janneke was raised to be the male heir. While her sisters were becoming wives and mothers, she was taught to hunt, track, and fight. On the day her village was burned to the ground, Janneke—as the only survivor—was taken captive by the malicious Lydian and eventually sent to work for his nephew Soren. Janneke’s survival in the court of merciless monsters has come at the cost of her connection to the human world. And when the Goblin King’s death ignites an ancient hunt for the next king, Soren senses an opportunity for her to finally fully accept the ways of the brutal Permafrost. But every action he takes to bring her deeper into his world only shows him that a little humanity isn’t bad—especially when it comes to those you care about.

In a cottage high atop Llanfair Mountain, sixteen-year-old Clara lives with her sister, Maren, and guardian Auntie. By day, they gather herbs for Auntie’s healing potions. By night, Auntie spins tales of faraway lands and wicked fairies. Clara’s favorite story tells of three orphan infants Clara, who was brought to Auntie by a stork; Maren, who arrived in a seashell; and their best friend, O Neill, who was found beneath an apple tree. One day, Clara discovers shimmering scales just beneath her sister’s skin. She realizes that Maren is becoming a mermaid and knows that no mermaid can survive on land. Desperate to save her, Clara and O Neill place the mermaid-girl in their gypsy wagon and set out for the sea.

Aidan desires only one thing: to rule. Arrogant, headstrong and driven by the element of Fire, he will stop at nothing to bring the evil Howls that destroyed Scotland to their knees. But Fire is a treacherous element, and the very magic that brought him to power could burn his world to ash. Especially with the blood of his fellow Hunters on his hands. Driven by a bloodlust he can’t control and dark whispers that may not be entirely in his head, he and his magic-eschewing friend Kianna will do whatever it takes to liberate their broken world. Even at the risk of confronting the Church. Even at the risk of losing his humanity.

Most people have no idea goblins live in the woods around the small town of Bellwater, Washington. But some are about to find out.

Her older sister, Livy, is at wit's end trying to understand what's wrong with her.
