One of the many engineers that keep Beta, the city under the sea, running, Mira only wants to make her family proud and to prove herself worthy. She knows the mysterious city better than anyone and it's her dream to help it flourish. Then, on a solo job in an abandoned section of the city, she encounters a monster of legend: an undine, a dangerous merman from an ancient civilization, long forgotten.

Known as a harbinger of bad omens and blamed for Demons eating her family, Reia is shunned by her entire village. When the next offering is due and the monstrous Duskwalker is seen heading their way, her village offers her an impossible choice—be thrown into the prison cells or allow herself to be sacrificed to a faceless monster.

When my father wanders into the enchanted realm of the fae, I know I have to go after him. And when he gets imprisoned, I'll do anything to save him, even trade my freedom for his. I had no idea I'd end up imprisoned by four sexy fae who turn into beasts at night.

I’m a wielder of hearts and summoner of corruption. Heir to nothing and born to a fool in the wrong damn month. But I’m also one of only two Fae in this divided land of hellions who might be starting to see through the lies we’ve swallowed for so long. In the year we turn twenty-one, conscripts from across the warring nations of air, fire, earth and water are sent to Never Keep – the only place in our besieged continent where our magic can be Awakened. But something is wrong inside Never Keep. Something which might extend far beyond the reaches of this desolate fortress.

Sentenced for a crime she didn’t commit, Samara is bullied by guards and tormented by the screams of her fellow prisoners. She’s resigned herself to enduring her fifteen-year term… until she learns that the freedom she's been promised is the cruelest lie of all. Now she's faced with a choice: resign herself to dying in the cold walls of Castle Greymere, or do the unthinkable and escape. But no one leaves Greymere alive. So to break out of the prison? She’ll have to use one of the undead.
