The Bloodless Boy by Robert J. Lloyd

Amid the panic of the Popish Plot in 1678 London, the corpse of a young boy found drained of blood draws a Royal Society natural philosopher and his assistant into a perilous inquiry that links clandestine transfusion experiments, political machinations, and sectarian zeal. As they navigate court intrigue and a city still scarred by plague and fire, their pursuit of evidence pits reason against rumor and places them in the crosshairs of powerful men determined to bury the truth.
