I would love comprehensive books but books that cover not just their upbringing but their times in office
A lot of the great books only cover their life and not their decisions in office and political views, etc...
The first two that came to mind were these two:The Years of Lyndon Johnson by the American writer Robert Caro.
Team of Rivals: The Political Genius of Abraham Lincoln by Doris Kearns Goodwin
Amazon has a nice list two. https://www.amazon.com/Best-Sellers-Books-US-Presidents/zgbs/books/9681307011
