After finding out she is the Bellata-the prophesied warrior meant to save Decim-Addie, along with James, returns to Barracks to unite the Twelve Magisters. But as she discovers her old home in ruin, Addie stumbles upon Silas and Nana, the only people left in Barracks.

As Silas explains what happened, Addie remembers the special gift Eman entrusted to her. She gives the gift to Silas, only to learn that he's the young blacksmith who fought through the Seven Choices, making Addie unsure of how to react to her old friend.

Dodging an attack from Schism, and another deadly ally to Ophidian, the group finally makes their way to Ramni, where a familiar face joins them-one Addie never wanted to see again.

If Addie can't learn to balance her new power, successfully unite the Twelve Magisters, and figure out what's going on with a new voice in her head, Ophidian will destroy all the twelve lands ...

And she'll never know who is capable of betrayal amongst her friends.
