Curse Breaker by Audrey Grey

All magic has a price.

Haven survived the Devourers, but she isn’t any closer to breaking the curse. Meanwhile, her forbidden magic rages brighter and more dangerous every day.
To control her powers and stand a chance against the Shade Queen, Haven made a bargain with two enemy immortals. Now her waking hours are spent fighting alongside the Sun Lord, but her dreams belong to the Shade Lord.

Only the closer she ventures into the wicked Shadow Kingdom the more her magic shows itself—and the more she struggles with whom to trust. The golden but wounded Sun Lord or the darkly charismatic Shade Lord.
Both are off-limits.
And both have the ability to save her . . . or destroy her.

With the Shade Queen closing in and Bell’s time nearly up, Haven will sacrifice everything to break the curse—but will it be enough to stop the mortal realm from falling into darkness forever?

Welcome to the Kingdom of Runes where immortals and humans clash, light and dark magic reign, and mythical creatures lurk in the shadows.
