Fae and humans alike are returning to London for the Season, but the excitement is marred by the growing poverty rate among humans with low magical scores.

Tenacious Roger Barnes proposes a new rubric for testing magic to the Council, hoping to resolve the predicament for his fellow humans. But when he is paired with Wyndham Wrenwhistle, a dashing fae who has disliked him since childhood, the project seems destined to fail. Even after reaching a tentative truce, their fragile partnership crumbles due to malicious lies.

Adding to the disarray, a popular gossip column unexpectedly announces that Roger and Wyn are engaged. Obliged to go along with the falsehood to save their families from scandal, they are forced to reconcile their differences for the sake of the rubric - and for their impending marriage. As the project bleeds into their wedding plans, the pressure to flawlessly execute both mounts even higher.

Together, they have the chance to solve a crisis decades in the making - but they'll need more than magic to succeed.
