The Haven, the Hallow, & the Highborn by Jessa Grey

In facing her finest opponent, she will uncover her greatest strength.

Eedy Blackthorn wields a rare and mystical witch magic—she can become a conduit to harness the raw forces of lightning itself. But her abilities do not make up for her painful past. After a tragic accident claims her beloved father, Eedy inherits his seat on the mage-led council. Consumed by guilt over her father’s death and determined to honor his legacy, she refuses to be silenced, no matter how often the male-dominated council disregards her suggestions.
When a mysterious disruption in magic threatens the kingdom’s balance, Prince Caelum is sent to join the council. Discovering Eedy’s identity reawakens a grudge tied to her late father, who ridiculed his family for years. With old wounds resurfacing, every council debate between them crackles with tension. As they clash over how to restore the magical order, their arguments become charged with something neither of them is willing to name.
With duty and destiny colliding, Eedy and Caelum must navigate their forbidden feelings for each other while racing to restore the kingdom’s magic before the winter solstice. As the solution to the magical crisis becomes clear, the couple is faced with an impossible decision, one that will test the limits of Eedy’s power and the depths of Caelum’s heart.
