For all you "Gone Girl" fans...

I just finished Gillian Flynn's "Dark Places"... great book... nice follow up to "Gone Girl" I'm now reading, "Before I Go to Sleep"  by S.J. Watson... if any of you have read it.. let me know if its good.. so far so ehhh it reminds me of Momento... .I also have "Night Circus" and I just got "The Kill Room" if anyone has a book to recommend let me know... I would love  a good one!!!
