A Relentless Rake

Harrington takes her Regency era Lords of the Armory series to new heights with this un-put-downable fourth romance (after An Extraordinary Lord). Alexander Sinclair, Earl of St. James, and his illegitimate half brother, Nathaniel Reed, are tapped by the Home Office to uncover the latest plot by Scepter, a criminal organization dedicated to overthrowing the monarchy. Their only lead is a clue left at a meeting of Scepter’s members: a scrap of paper with obscure calculations, building plans, and the name Everett. Alexander makes the connection to the Everett School, a girls’ school run by mathematician Henry Everett and his sister, Olivia. As he investigates, Alexander can’t help but be intrigued by Olivia’s beauty and intelligence, discovering that she’s the brains behind Henry’s application for a fellowship at the Royal Society. As he grows closer to uncovering Scepter’s plans and the danger increases, so too does the chemistry between Alexander and Olivia, leading both to reveal their deepest secrets and emotional scars. Harrington’s alluring characters and their mysterious pasts easily draw readers into the narrative, while the looming threat of Scepter keeps the pages flying. This may be Harrington’s best yet.
