I'm working through "Haskell: the Craft of Functional Programming" (by Simon Thompson) in depth, and I want to put in a good word for it. His exercises are numerous and they seem to lead me from simpler ideas to more complex ideas in a natural way. As part of learning Haskell, I actually started with other books and tutorials and skipped around in them, reading some of the later chapters before the earlier ones. I like that sometimes. But I'm finding that Thompson's book is helpful for getting an intuition for the language, as opposed to just reading about its features, so I'm working it in order. My other books include "Real World Haskell" and "School of Expression." The wonderful thing about RWH is that it's available online (I do own a hardcopy) where people comment on the text and exercises. -Mike
