Suggest me some page-turner books (preferably non-romantic)

I've spent the past month reading roughly 9-10 books. This month I have completed 4 books already but since the past couple of weeks I have not been able to read.....anything.

I want to get back to reading. I usually read genres like slice-of-life or contemporary literature but I am looking for more thriller and mystery books. Not those mystery books that have two characters romancing on the side and the plot just shifts to them leaving the mystery stale. I am looking for a simple yet thrilling book that has a good plot and decent characters.
