The Science of the
Perfect Shelf.

Most algorithms just show you what everyone else is buying. We believe a truly great recommendation should surprise you.

The Echo Chamber

If you liked The Hunger Games, most sites will just tell you to read Divergent. While that's accurate, it's boring. You get stuck in a loop of the same 50 bestsellers. SleeperStack was built to break that loop. We analyze books not just by genre, but by trope, mood, pacing, and atmospheric "vibe."
