Dropping by to post some more recommendations
The first two are Indies.
The Wayward Pines Series by Blake Crouch (I am eagerly awaiting the third book which I hopefully will have in my hands by the end of the week)
Forsaken by Andrew Van Wey- Don't be turned off by the negative reviews that mentioned spelling, grammar and wording issues. The writer has since cleaned up the book and the copy that I read was pretty much error free. If you love horror/thrillers this is a great read.
I am going to have to second Inferno By Dan Brown, after Bignuf recommended it I moved it to the top of my read pile and ended up absolutely loving it.
I actually have been recommending that book like crazy to friends, family and co-workers. lmao
