The notoriously eccentric Lord Christopher Eden is a "man of unusual make" and even more unusual habits: he prefers to live far from the prying eyes and ears of the ton, and would rather have the comfortable company of his childhood cook and his aged butler than the swarm of servants and hangers-on befitting a man of his station. But Christopher's pleasant, if occasionally lonely life is upended when he receives word from his lawyers that, according to his late father's will, he must find a wife by the end of the Season if he intends to keep his family's fortune and the Eden estate. Christopher cannot imagine a worse fate: as he isn't attracted to women, his chances of making a wife happy are slim. Furthermore, if his quest to marry has any hope of succeeding, he must move to London posthaste and acquire some more suitable staff.

Enter James Harding, Christopher's new, distractingly handsome--if rigidly traditional--valet. After a rocky start, the two strike up a fragile friendship amid the throes of the London Season . . . a friendship that threatens to shatter under the looming shadow of Christopher's impending nuptials--and the secrets both men are keeping. With its heady combination of dry wit, slow-burn romance, and a nuanced portrait of trans identity, A Gentleman's Gentleman stands to transform the historical romance genre as we know it.
