As Christmas hurtles towards us like an oncoming train, we're sure that you're on the lookout for something to give that proves you've read a book this year. Amazon just published its list of the 20 best selling books of this year, which feature some returning titles from their midyear list Topping the charts, shock of shocks, is Harry Potter & the Cursed Child. And while it's no shock that a Harry Potter title would dominate sales, this is the first time that a script has found its way into the top 20.The other titles on the list are somewhat surprising as well. When Breath Becomes Air by Paul Kalanithi, a memoir by a late neurosurgeon about his battle against lung cancer, comes in second. The top-selling debut novel is The Nest by Cynthia D’Aprix Sweeney in the 17th position. Other notable books include Before the Fall by Fargo showrunner Noah Hawley and, since it's 2016, Crisis of Character: A White House Secret Service Officer Discloses His Firsthand Experience with Hillary, Bill, and How They Operate by Gary J. Byrne. Crisis of Character has largely been discredited and dismissed as mostly hearsay (if not untrue), which actually makes it a perfect book for this election cycle.
