Children of Gods & Monsters (The Aurorian Triology #2) by Lacie M Lou:
 
Magic has returned.
New dangers emerge.
All is not well in Hevastia.

Eliana only wanted to restore her people's gifts, she never intended to release Vaiccar from his prison. Now, she's set a target on all their backs.

Vaiccar has seized control of the Haematitian Council and the Morei warriors. His darkness spreads more furiously through Hevastia as those with magical gifts are hunted.

Fearing her magic alone won't be enough to stop Vaiccar, and struggling to accept the fates of Kai and Cire, Eliana and her friends set off on an epic adventure in search of answers, and powerful allies for the looming war.
