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.

To enter the woods as a human means death… But I am no mere human. They call me, “witch.” As one of the last surviving witches, Faelyn’s sole duty is to keep the protective barriers on the forests where the lykin roam—creatures who can shed flesh for fur—sparing nearby humans from their violent, beastly natures. When she has an unlikely encounter with the rare, primordial spirit of the moon, Faelyn finds herself not only the object of the Wolf King’s desire, but essential to his ability to keep his crown.

For twenty years, I’ve been an unwanted changeling. I have no name, no family, and no answers. Until an irresistibly wicked faerie begins a seductive game of cat and mouse. I am his prey. His treasure. A perfect pet. He offers a trade: he will take me to the faerie realms to assist in my search for the truth of who I am. In return, I must agree to marry him. But things are not as they seem, and soon after arriving at his wintry manor, I begin to unravel a dangerous web of lies.

Born into a life of duty and sacrifice, Morgan Pendragon's destiny has never been her own. Rumored to carry the tainted blood of the fae in her veins, her birthright was stolen from her when she was a mere child. Growing up in the shadow of her brother, the king, she has been promised to the goddesses when she comes of age. So, when her brother commands that she seek out a fae weapon of legendary power, Morgan seizes the chance to break free from the chains of her fate.

My father called them messengers. He once told me they walked among us and that somewhere in this dark and godless city, there shined a faint sliver of hope. I had only to look for the signs. Well, I’ve spent my whole life investigating the inexplicable and all I've found are the unsettling vestiges of iniquity—the evidence of another world shrouded by the obscure. Purgatory to some, where depravity hides in shadows, and girls like me are little more than delicious bites of temptation. Others call it Nightshade.
