Every Thriller I have read, was Predictable. I want something That blows my mind.

The Books I have read are,

Silent Patient
Before I Go To Sleep
Kind Worth Killing
Kind Worth Saving
Housemaid

there are other, but those are Science Fiction with Thriller, but I like to read something grounded now.

The Kind Worth Killing duology was great. I loved it. It was awesome. Now, the Twists in that series are a bit different. Because the Author plays with a Surprise Character than an Surprising Event. I loved that, but still, I need something that makes me feel flabbergasted.
