Not sure if I know something similar, but here are some Books I would recommend:
for some heavy reading :
House of Leaves by Mark Z. Danielewski
Infinite Jest by David Foster Wallace
Cryptonomicon by Neal Stephenson
Less Heavy:
The Wind Up Girl by Paolo Bacigalupi
Super Sad True Love Story by Gary Shteyngart
Light Reads:
Bite Me by Christopher Moore
Dresden Files Books by Jim Butcher
Culture books by Ian M Banks
thats what i got off the top of my head. I tend to read a lot too, so hit me up if you want more suggestions!
and from the style of the book you described above (havent read it), look for a short story called Flowers to Algernon. Similar style i think. But its a very well known short story, so I think you know it
