I've scanned nearly all published F# books, among them I suggest:
Expert F#, read it after you have learned enough basics and have programming experience with F#. Don't use it as a tutorial book, F# has changed in the past two years, the code in this book usually needs some modification to run in the new compiler.
Programming F#, a great book for beginners, if you want only one book to start, this one is best.
F# for scientists, learning F# from a scientific perspective. it shows you how to use Seq, List, Array, these basic things to build a complicate functional program in F#.
Real World Functional Programming in .NET, learning F# by doing projects.
