Ooh, thanks for suggestions for my "to read" list! As if the list wasn't long enough already! Had not heard of "Gone Girl" but will look for it.
Here are my suggestions:
"Night Circus" by Erin Morgenstern. Yeah, I didn't think I would enjoy it either, and almost returned it to the library without reading it, but picked it up one night...and was immediately drawn in. Really recommend it.
"The Absolutely True Diary of a Part Time Indian" by Sherm Alexie. It's another Y/A book, but a wonderful read. Very unique writing style, and is funny/sad/thought provoking. Please read it.

There is also a very enjoyable, but different , series by Colin Cotteril. One of the books is titled, "The Curse of the Pogo Stick". They star Dr. Siri Paboun, a Dr. who is named national coroner in communist controlled Thailand, though he has never been a coroner before. They are mysteries, and very well written. Probably doesnt sound good by my description, but they are!
Other books I have enjoyed are Water for Elephants, Patricia Cornwell's Kay Scarpetta series, the Alexander McCall Smith No.1 Ladies Detective Agency series, and, and, and...ok, I'll stop here.
Happy late summer reading!
