Shadow of the Sending by A.M. Kay

A shadow storms inside Lyvia, all-consuming and unyielding to her transformative light, as two of the mightiest powers in the Realm of Vael struggle to coexist.
After retreating from a devastating loss at the Battle of Odessa, the crew of the Evecta and soldiers of the Rising grow restless in the elven Queendom of Lotrennia. Though they’ve found refuge, Queen Antares rules her court with cunning words and calculated wit. Lyvia must navigate dangerous politics as she attempts to gain control over her newfound powers, dethrone King Saros of Sultira, and save the souls of the ashen.
But as news of mysterious deaths spread in Lotrennia, what remains of Lyvia’s humanity is exploited, setting in motion events that cannot be undone. The hunt for the next bone of power will push Lyvia to her limits, forcing the Bellator to make choices that will shape the future of her world and who she is.
Oaths will be sworn, bonds will be broken, motives will be revealed, and salvation will rest in the hands of the enemy. Lyvia must learn to live with the decisions she’s made, and accept herself despite them, as the shadow of the Sending begins to eclipse her very soul.
