I'm not familiar with any of these authors. I tried to include all authors I read this year that were new. It's surprising how many! https://girlof1000wonders.wordpress.com/2016/12/06/top-ten-tuesday-for-the-first-time-in-2016/
I haven't read any of these yet but you can check out my list here. https://runwright.net/2016/12/07/new-favorite-authors-in-2016/
I've really like Riggs - Can't wait to see what he does next! Great picks!
I read Ransom Riggs for the first time this year, too! Totally forgot about him. Great list!
