So, basically, the challenge is to submit one book recommendation from each year the Read-A-Thon was running (2007-2017). This is gonna be a challenge because I've only been keeping track of my reading for the past few years! Wish me luck!
2007 - Chimichanga by Eric Powell
2008 - Hellboy: The All Seeing Eye by Mark Morris
2009 - I Kill Giants by Joe Kelly, J.M. Ken Niimura
2010 - How to Live Safely in a Science Fictional Universe by Charles Yu
2011 - The Tower's Alchemist by Alesha Escobar
2012 - WBI: Witches Bureau of Investigation by Richard Capwell
2013 - The Science of Monsters by Matt Kaplan
2014 - The Mirror Empire by Kameron Hurley
2015 - RunLoveKill by Jonathan Tsuei, Eric Canete, Leonardo Olea
2016 - Outriders by Jay Posey
2017 - Under the Pendulum Sun by Jeannette Ng
I can verify that, to me, all these books were highly entertaining and engaging!
