Pop your favorite Agatha Christie whodunnit into a blender with a scoop of Downton Abbey, a dash of Quantum Leap, and a liberal sprinkling of Groundhog's Day and you'll get this unique murder mystery. The twisting, cleverly-written debut revolves around Aiden Bishop, forced to relive the day of socialite Evelyn Hardcastle's murder over and over until he can track down her killer and break the cycle. The trick? Each day Aiden finds himself reliving things in the body of a different guest at Lord and Lady Hardcastle's masquerade, making the information he's able to gather and the relationships he forges in his search increasingly complicated.
