I am currently reading All Clear by Connie Willis. It is the conclusion to the time travel novel Blackout which begins in 2060. Historians allowed to go back in time to research various events from the past. In Blackout a group of historians travel back to different events during World War II in London and the surrounding areas. The historians are not always together and the chapters jump from character to character and year to year. At times it can be a little frustrating to follow, but if you keep trudging through the storyline makes sense and is completely engrossing. I did not know a great deal about World War II (especially in London) but find myself constantly thinking about the well developed characters and storyline.
