I’ll bite.

Out of ~15 CS books read, my top pick would be “Learn You A Haskell For Great Good”.

Admittedly most of the CS books I have read are these instructional, O’reilly style books (often teaching a specific language) as opposed to academic texts. But regardless…

It’s a well written book. It introduces Haskell in a comfortable way, at a good pace. And I do like the humor. Or at least, I did when I read it years ago.

It’s also one of the few language specific books that I felt generally broadened me as a programmer. Worth a read regardless of whether you intend to actually use Haskell.
