«Right Place, Right Time» by K.M. Mahoney

All the time in the world is still never enough. In the heart of London in 1349, an apothecary engages in a futile battle against the rising tide of death brought on by the Great Pestilence. For this man, however, the duties of his profession are accompanied by an even greater responsibility-find Henry and ensure he survives the worst of the epidemic sweeping the Western world. Now if only Dr. Drake Stilson knew which Henry to save. As an employee of The Oracle Group, a military and scientific organization dedicated to correcting the damage done by people playing around with time travel, this is far from the first time Drake has been sent to a distant time and place and expected to do the impossible. This is the first time, though, that he's felt as if the battle is lost before it even begins. Surrounded by fear and loss, Drake is on the verge of surrendering to the inevitable when disaster strikes. Despite being partners in work and life, Jens Pakkala rarely gets to spend time with Drake. He would love to take his partner and walk away from The Oracle Group, but how can he ask a dedicated historian to give up the opportunity to live out his studies? Then Drake runs into trouble on his latest assignment and Jens world begins to crumble. Now he has to figure out how to get himself to the right place and time to save Drake and bring him safely home.
