The thread on Amazon Prime's price hike reminded me about Kindle first. I haven't gotten a free book since January and completely forgot about it so I just got my free book for the month of March. I thought I signed up to get email alerts, but maybe I accidentally deleted it. For Kindle users, which book are you thinking of getting/did you get?

I got Hidden because it got the best reviews, and the summary intrigued me. The other 3 books look scary, and I don't usually read thriller genres unless it's very very popular bc then my curiosity gets the best of me (like The Girl in the Dragon Tattoo series).
