Reading Freely 
Can I recommend reading about that “shithole” Haiti. As tragedies several hundred of years of French rule and American interference, invasions and abuse. And then a catastrophic earthquake which killed hundred of thousand and destroyed nearly everything. My son went there shortly after and described what he saw and how little aid was coming in. That's not what American media portrayed…:(
Yes, I'm hoping to find something that covers Haiti and the D.R. together, since they're neighbors on the same island. (Did your son make any mention of Doctors without Borders? Their literature at the time was intensely focused on Haiti relief efforts.)
Glad you've found the Mount TBR Challenge. Good luck with your TBR of Doom!
Thank you for hosting, and good luck to you as well!
