Jacob Sager Weinstein is the author of four non-fiction books for adults and has written for The New Yorker, HBO and the BBC. He is also a former contributor to The Onion and has won a Writers’ Guild of America Award.

The idea for City of Secret Rivers came to Jacob while walking along the Thames Embankment, as he started thinking about London's secret underground rivers and "discovered that London's history is so magical that it only takes the slightest of tweaks to make it into a fantasy story."
