I recommend “The Devil in the White City” which interweaves the story of planning and building the 1893 Chicago World’s Fair with that of a serial killer....
And “In the Garden of Beasts” about the rise of Hitler and the Nazi party as seen from the viewpoint of the American Ambassador to Germany and his family.
Both by Erik Larson.
For light reading: anything by Robert B. Parker (miss him - and Vince Flynn...), Robert Crais, David Baldacci and Michael Connelly.
In the Garden of the Beasts was indeed a winner.
