Song of the Dead by Sarah Glenn Marsh

The Dead must stay buried.

Karthia is nothing like it used to be. The kingdom’s borders are open for the first time in nearly three hundred years, and raising the dead has been outlawed. Odessa is determined to explore the world beyond Karthia’s waters, hoping to heal a heart broken in more ways than she can count. But with Meredy joining the ocean voyage, vanquishing her sorrow will be a difficult task.

Despite the daily reminder of the history they share, Odessa and Meredy are fascinated when their journey takes them to a land where the Dead rule the night and dragons roam the streets. Odessa can’t help being mesmerized by the new magic–and by the girl at her side. But just as she and Meredy are beginning to explore the new world, a terrifying development in Karthia summons them home at once.

Growing political unrest on top of threats from foreign invaders means Odessa and Meredy are thrust back into the lives they tried to leave behind while specters from their past haunt their tenuous relationship. Gathering a force big enough to ward off enemies seems impossible, until one of Queen Valoria’s mages creates a weapon that could make them invincible. As danger continues to mount inside the palace, Odessa fears that without the Dead, even the greatest invention won’t be enough to save their fates.

In this enthralling, heartrending sequel to Reign of the Fallen, Odessa faces the fight of her life as the boundaries between the Dead and the living are challenged in a way more gruesome than ever before.
