I just released the 5th edition of my book "Loving Common Lisp, or the Savvy Programmer’s Secret Weapon" https://leanpub.com/lovinglisp - this is a free upgrade for previous purchasers.

If you purchased a previous edition and did not get a notification letter from leanpub.com, then please manually login to your leanpub.com account to download the new edition.

thanks a lot for your effort.

I'll read this new version too.

I think your book is very underestimated. It's a great book to beginner perhaps the best one, because It's updated and It's very practical. If I would have to recommend someone about where to start to learn Common Lisp I'll say to start with your book.

Thank you!
