The Hurricane Wars by Thea Guanzon

The fates of two bitter enemies with opposing magical abilities are swept together in The Hurricane Wars, the spellbinding debut in a fantasy romance trilogy set in a Southeast Asia–inspired world ravaged by storms, perfect for fans of Fourth Wing and A Court of Thorns and Roses

The heart is a battlefield.

All Talasyn has ever known is the Hurricane Wars. Growing up an orphan in a nation under siege by the ruthless Night Emperor, she found her family among the soldiers who fight for freedom. But she is hiding a deadly secret: light magic courses through her veins, a blazing power believed to have been wiped out years ago that can cut through the Night Empire’s shadows.
Prince Alaric, the emperor’s only son and heir, has been tasked with obliterating any threats to the Night Empire’s rule with the strength of his armies and mighty shadow magic. He discovers the greatest threat yet in Talasyn: a girl burning brightly on the battlefield with the magic that killed his grandfather, turned his father into a monster, and ignited the Hurricane Wars. He tries to kill her, but in a clash of light and dark, their powers merge and create a force the likes of which has never been seen.
This war can only end with them. But an even greater danger is coming, and the strange magic they can create together could be the only way to overcome it. Talasyn and Alaric must decide… are they fated to join hands, or destroy each other?

An exquisite fantasy brimming with unforgettable characters and sizzling enemies-to-lovers romance set in a richly drawn world, The Hurricane Wars marks the breathtaking debut of an extraordinary new writer.
