Dark Wizard by Jeffe Kennedy

Lord Gabriel Phel wants one thing: to restore his shattered House to its former station in the Convocation’s complex and arcane society. Fortunately, through a wild chance of birth, he was born with the magic of a powerful wizard, the first in his family in generations. If he can obtain a familiar to supplement his skills, ideally one who is a highborn daughter who can also be his lady wife, then he’ll be that much closer to restoring House Phel. And to exacting his ultimate revenge on the Convocation that destroyed his family.

Lady Veronica Elal doesn’t have many choices. To her bitter disappointment, she will never be the powerful wizard she and her father hoped she’d be. Instead Nic is doomed to be a familiar like her mother, a second-class citizen in the Convocation, and one destined to be bonded to a wizard, serving his purposes for the rest of her life. Her one hope lies in entering the Betrothal Trials—and choosing a wizard from the Convocation candidates that she can manipulate. Whichever one of her suitors impregnates her will claim her as familiar and wife, and she can use her wiles to rule her wizard master, and the House she marries into.

But Gabriel throws a wrench into Nic’s careful scheming, by seducing and fascinating her. When she finds she’s pregnant by the rogue wizard she can never hope to control, Nic does the unthinkable: she runs.
