Marked By Lightning by Jessamyn Kingley

When a group of intrepid sorcerers leaves their government, Prism Wizard Vadimas Porfyra is selected to lead them. After centuries of denying his chosen school of magic, Vadimas is embracing the full power of his hue. Busy ruling the Spectra Wizardry, he believes the only thing missing from life is a tidier house. Treasured by the large D’Vaire family, Vadimas is content and not seeking anything beyond knowledge.

Far from the Council of Sorcery and Shifters is Arch Wizard Severin Dewitt, the Fate-chosen leader of the wizards. Little is known about the man whose wrist is marked by lightning. Severin is rarely seen, and unbeknownst to most, inside a house he cannot leave, his every move is being watched. Yearning for freedom, Severin must take matters into his own hands to forge his own destiny.

The Consilium Veneficus considers Vadimas an upstart and a traitor, so when he and Severin find out Fate has chosen them as a couple, there is little consensus on what the future holds. Severin’s knowledge of Fate is minimal, making it difficult for him to accept that a matebond rises above everything, while Vadimas trusts her fully, pushing their relationship to the brink.
Will distance, separate goals, and the ocean separating their populations of wizards stand between Vadimas and Severin forever, or can the two compromise to build a future together?
