Full disclosure: I worked on this book as an editor and research assistant. (I don't have any referral links, and don't earn any money from extra sales, btw.)
It's awesome. Think many of you guys would appreciate it.
Nik has a great story about money: being banking + technology, and accounting for the rise of the (euro)dollar and ending up in bitcoin.
It was a lovely manuscript to work on, and a great product altogether.
Highly recommend. Go order the book.
