Queens of Woven Fates (Vessels of the Gods #2) by Katerina Stevens:
 
Claiming the crown was only the beginning…

Surrounded by a Royal Council she does not trust, and fearing that her magic was corrupted by a nefarious spell book, Queen Absolute Esmeray must rebuild her tarnished reputation from the ashes of her ruthless rise to power. But the Dark Queen has made many enemies, and she swiftly learns the price to keep the throne is higher than she ever anticipated.

While embracing her newfound freedom, Lenna worries her returning migraines are a foreboding sign that a dangerous prophecy is coming to fruition. And when she is confronted by a mysterious stranger, Lenna realizes just how tangled the threads of the past are - especially when the gods get involved.

Across the sea, Orla struggles to adjust in a magic-imbued land. With no way home, she is brought before the Prince and given an ultimatum. To escape a terrifying fate, Orla must utilize every bit of her cunning - even if it means accepting truths she is determined to conceal. But the arrogant Prince watches her closely, beasts of myth converge on the Kingdom, and Orla's only chance at survival may very well be the magic she fears most.
