Shadow Fall by Audrey Grey

My name is Maia Graystone: prisoner, rebel, and reluctant savior of a dying world. In exactly 552 hours, an asteroid will end life as we know it. Not that I'm counting or anything. Trapped inside a hellish prison with thieves and murderers, I have more current worries. Like the brother I left behind or the not-so-friendly inmates or the fact that I'm wanted by the most powerful man in existence. 
Then a mysterious benefactor breaks me out and offers the impossible: a spot in the Shadow Trials. Win and I'll receive a coveted place for my brother and I on the space station in the stars. But the opportunity comes at a steep price. Partner with a dashing psychopath, enter the court that once condemned me to death, survive the ruthless trials created by my own mother, and kill the Emperor--the very man who's hunting me. In this cunning game of life and death, nothing is as it seems and everyone expects me to fail. But they forgot one tiny detail. Never underestimate the girl with nothing left to lose.

Curse Breaker: Kingdom of Runes Book 2 by Audrey Grey

Perfect for fans of Sarah J. Maas and Holly Black, this enemies-to-lovers adventure romance should come with a book hangover warning. 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?
