The Final Queen (en Inglés) - JM Langan

Her king is dead. War is coming. And something ancient and evil is stirring.

Catharina has lost the one person who held her world together, but grief is a luxury she can no longer afford. As enemies gather and darkness creeps across the realm, she must uncover whether there is any way to bring her king back.

With kingdoms on the brink and the final battle drawing near, Catharina must decide how much she is willing to sacrifice for love, for power, and for the crown.

When the winner takes everything, will Catharina rise as queen-or lose everything she has left?
