Tested by the gods, Leda and her angelic mate Nero venture into the City of Ashes, a fallen fortress in the Western Wilderness where nightmarish monsters reign supreme and an ancient secret is buried. To survive the Gods' Trials, they will have to save the city - and they will have to do it without their magic. Their victory, however, comes at a heavy price. And the secret they uncover will upset the balance of power between Earth and heaven.
One year after joining the Legion of Angels in New York City, Leda Pierce returns home to visit her family in Purgatory, a rough and rugged frontier town that borders the plains of monsters. Leda's family reunion is cut short, however, when her little sisters are captured by supernatural mercenaries. Together with her angel lover Nero, she sets out to save them. Besieged by monsters, assailed by powerful foes, Leda knows this rescue mission won't be easy.
Cadence Lightbringer has everything. The prestige and power that comes with being the Angel of Storm Castle. Her archangel husband and soulmate, Damiel Dragonsire, Master Interrogator in the Legion of Angels. And their son Nero, a miracle of magic, the first and only child of two angels. But the Legion's mission to exterminate dark magic brings trouble to Cadence's door. What begins as a mission to apprehend a rogue angel escalates into a hunt for ancient relics that will turn her life upside down.
The original Immortals, masters of magic, once reigned over every world in the known universe - until they suddenly vanished. The gods and demons have been fighting over the remains of their fractured empire ever since. Millennia later, new angel Leda, a soldier in the gods' army, is recuperating from her transformation. Her recovery is cut short, however, when a curse strikes New York City, a spell targeted directly at the Legion of Angels. Even as the Legion's soldiers succumb to wrath, jealousy, and fear, the beasts on the plains of monsters are growing in numbers and power.
Cadence Lightbringer, daughter of a legendary archangel, has always known her gods-endowed magic comes with a price. As an angel in the Legion of Angels, she lives where the Legion commands her to live, trains how the Legion tells her to train, and marries whom the Legion instructs her to marry. Somehow it all sounded simpler in her head. When Cadence is ordered to marry the enigmatic angel Damiel Dragonsire, a man she hardly knows, her whole perfect, predictable life is turned upside down.
The games of gods play out upon the backbones of mortals. Leda Pierce has come a long way since she left her home on the frontier of civilization one year ago to join the Legion of Angels. She is a soldier in the gods' army, has crossed swords with demons, and shares an apartment with her angel lover in New York. Every day brings Leda closer to becoming an angel herself - until a promotion ceremony goes horribly wrong, leaving her powers in magical limbo. Worse yet, the gods have taken over her training at Crystal Falls.
Cadence Lightbringer, daughter of an archangel, has trained from birth to one day drink the Nectar of the gods and ascend to the angels' ranks. She's always been the perfect soldier. She's always known exactly where her life is headed. Until she is assigned to a mission with Damiel Dragonsire, Master Interrogator of the Legion of Angels. Powerful, paranoid, and brutally intelligent, Damiel has built up a reputation for hunting down each and every traitor hiding within the Legion's ranks. And his latest suspect is Cadence.
Leda Pierce has survived the gods' first test and gained entry into the Legion of Angels, but the fight is far from over. Someone is poisoning the supernaturals of New York. Suspecting witches, the Legion sends in Leda to investigate. To save the city, she will need magic she doesn't have - and gaining that magic might just kill her. Now her survival depends on accepting help from the darkly seductive angel Nero, but that help comes with a price she cannot afford to pay.
Leda Pierce is working as a paranormal bounty hunter on the Frontier, the dividing line between human civilization and the plains of monsters. Life is simple until a vampire hunt goes wrong and her brother goes missing, captured by the dark angels of hell. With no magical powers of her own and no way to find him, Leda's only option is to go to New York and join the Legion of Angels. If she can survive long enough to make it up the ranks, she will gain the magic she needs to find her brother.
Leda Pierce's latest mission brings her back to her hometown at the edge of the Frontier. But things have taken a turn for the worse in the six months since she left home to join the Legion of Angels in New York City. Crime lords now rule over the town, and the beasts' numbers are exploding just beyond the great magic wall that separates humanity from the plains of monsters. Together, with the fiercely seductive angel Nero, Leda guides a group of pilgrims across the monster-infested expanse to the ruins of the final battle between gods and demons.
Leda's quest to gain the magic she needs to save her brother leads her to the castle of the Dragons, home of four soldiers in the Legion of Angels with extraordinary powers over the elements. If she makes it through their training, she might just survive her next sip of the gods' Nectar and level up her magic. But the gods' gifts of magic come at a price. Leda can already feel the Nectar changing her, making her less human - and so is her budding romance with the angel Nero. Sip by sip, kiss by kiss, the change is taking hold of her.
