Welcome to Blackwood Academy: the legendary school located at the fringes of the afterlife, where students are fated to spend rest of eternity shepherding lost souls. Once a pupil enters the school's arched gates, there is no way out…except for the Decennial, a once-in-a-decade celebration that rewards nominees who pass its trials with a choice: formally graduate and join Blackwood's magical elite, or venture into the unknown and cross over to the mysterious Other Side.

There's a shortage of men in the kingdom of Amarra. After a failed rebellion against the matriarchy, most noblemen in the country are dead. Now the women of Amarra must obtain their husbands (should they want one) by kidnapping them from other kingdoms. Olerra, a warrior princess vying for the throne, is determined to prove her worth by kidnapping a husband. And not just any husband. To outmaneuver her treacherous cousin, she needs the best. Fortunately, the second-born prince of their greatest enemy is widely known for both his looks and his sweet, docile temperament.

The war may be over, but Hai Meilin is still paying a heavy toll. In spite of securing victory for the kingdom of Anlai, she is imprisoned upon her return. Her crime? Wielding a sword as a woman. In the palace, Meilin is an outcast and a social pariah. But beyond the imperial walls, the legend of the woman warrior has taken on a life of its own. To the east, a new rebel leader needs Meilin to helm his people’s revolution. In the south, a former enemy prince, now a prisoner of war, seeks Meilin’s aid in restoring balance to the Three Kingdoms.

Imogen Nel is in hiding. Hiding from a cruel kingdom that believes Sirens are monstrous, blood-hungry creatures. Hiding from a king and his captain who viciously hunt her kind. Hiding from her own alluring abilities. By keeping herself from the sea, Imogen’s bloodlust is dulled, and her black wings remain hidden beneath her skin. When a neighboring king comes to visit, Imogen can no longer hide. He knows precisely what she is, and he believes she can save both their kingdoms from an even greater monster. But Imogen’s power threatens to violently reveal itself, and the two form a blood bond.

Healer Anja regularly drinks poison. Not to die, but to save—seeking cures for those everyone else has given up on. But a summons from the King interrupts her quiet, herb-obsessed life. His daughter, Snow, is dying, and he hopes Anja’s unorthodox methods can save her. Aided by a taciturn guard, a narcissistic cat, and a passion for the scientific method, Anja rushes to treat Snow, but nothing seems to work. That is, until she finds a secret world, hidden inside a magic mirror. This dark realm may hold the key to what is making Snow sick. Or it might be the thing that kills them all.
