Intriguing -- what's the latter book? (The Monads in CoffeeScript one.) It sounds potentially interesting and useful, since I am *still* trying to truly wrap my brain around Monads, and some practical CS examples would be helpful.

I'm also currently (very slowly, in my spare moments) working through "Real-World Functional Programming With Examples in F# and C#", which is a nicely useful introduction to the subject for the .NET world. It's a bit slow, since it is starting from first principles, but not bad...
