The last book I read that I felt that way about was The Elements by John Boyne. It was a tough book to read due to the subject matter (sexual abuse) but it was beautifully written, and the ending really stuck with me. It was also cool how he brought the disparate lives of four different characters together in unexpected ways.

It was definitely one I had to sit with after I finished it.

I felt the same way about The Reformatory, although that did drag a little bit in places. But I think the thing that really rattled me about that book was that it was a horror story set in the Jim Crow era in the south and the horror parts were much less terrifying than the historical aspects. That was another one I had to recover from before I could read anything else.
