The stakes have never been higher for American heiress Gemma Lancaster Phillips, now firmly ensconced as both resident and employee of her ancestral estate, Cherrywood Hall. Together with her cousin Evan, 8th Marquess of Kentshire, and her boyfriend Kyle, the estate manager, Gemma wants nothing more than to pull off the royal wedding of the season while planning the premiere and U.S. tour for the period drama series, Castlewood Manor, and attending the Telly Tiara awards show. But an ex-love threatens Gemma's and Kyle's relationship, while the reveal of explosive secrets has the potential to shatter Gemma's relationship with her cousin and her future at Cherrywood Hall.

Jealousy and revenge mix with royal drama, power plays and scandal as the Tellys grow closer—with deadly results. Will Gemma, with the help of Scotland Yard, be able to put a stop to the mayhem? Or will the wedding, the tour, the Tellys—and Gemma's life—be ruined?
