Eric Normand - Grokking Simplicity: Taming complex software with functional thinking
I also bought the Scott Wlaschin book, but I must say I like Eric Normand's book a little bit better. Since the examples are also in JavaScript (but applicable to a lot of languages), I think it's easier to follow for everyone who's coming from an OOP background.
I'm also looking forward to Yehonathan Sharvit - Data-Oriented Programming: Unlearning objects.
