This listing is for two books by Carlo Rovelli: The Order of Time (9780735216112, 4th printing) and There are Places in the World Where Rules are Less Important Than Kindness (9780593192160, 1st printing). Both books are in excellent to nearly like new condition. The pages of The Order of Time are slightly yellowing just from sitting on a shelf. The back cover of There are Places in the World... has a very slight, unoticeable bend. Check out my shop for more science nonfiction!
