One year ago, when I first tried to learn Haskell, I looked at all the tutorials I could find online, and I always found myself lost when monads where being introduced... ... except with this tutorial (I read it online). It is the only one that really made me understand the concept of monad. The book takes you from functors to monads, explaining you how everything is pretty logical, and that if there were not there, you would probably have invented them.. If you ever tried to learn Haskell but could wrap your head around monads, this book is for you.
