Good D book

[Jeremy DeHaan]

I've been using D for a few months now, and i love it. It dawned 
on me that it would be nice to have some books to go over though!

I saw "The D Programming Language" by Andrei Alexandrescu on 
Amazon, and I almost bought it when I saw it was written in 2010. 
I know that D is under development, so would this book still be a 
viable option?

Are there any other books that someone would recommend?

Thanks much!
