[Haskell-beginners] book review?

has anyone read this book? beginners@haskell.org There are some mixed reviews on the product page. I'm a mid-level software engineer. I've only started learning about Functional programming (didn't even really learn about lisp in college) in the past 12 months. I'm looking to learn more about functional programming to help me improve as a programmer generally. Thanks, _Ramy
