Brace the Tide by Avril N. Sun

Book 1 in the Redemption series

Blurb:

The Daezh killed her father and marked her for death. Now Nadhya, a water mage from the small town of Lyria, must quietly assimilate into her new home of Allov, where the air is thick with the cult-worship of these transdimensional murderers. 

Fate brings her to three supernaturally adept allies - a quick and witty swordsman, a broody archer with unerring aim, and a dashing electromancer with a healing touch - each harbouring deep scars inflicted by her enemies. 

Banding together in their quest for vengeance, they enlist the aid of a wiley wizard, and Nadhya plunges into a deep rabbit-hole of enigmas that she can't easily crawl out of. After a rare encounter with a mysterious entity, and uncovering the darkness festering at the heart of the city, will Nadhya get her revenge, or will it all come apart at the seams?
