Adventures In Accounting
The Case of The Pigeon Pot Pie.
A Hollow Book Mystery
Nothing like hiding in plain sight. 
‘My life’ by Johnny Cash

No one is picking that up.
Ancient Semitic Civilizations
I’d be on that second one.
“Trump’s Greatest Tweets Vol. 2”
The Mathematics of Financial Derivatives. Not exactly bedtime reading, even for a quant.
