Do a search on Amazon for "Edge Animate book" and You will come up with quite a few, some newer than others - but most are not "recent" (2012-2013 is typical).
"Adobe Edge Animate: Using Web Standards to Create Interactive Websites 1st Edition" by Simon Widjaja came out in Dec 2013, though the inside pub date says 2014.
The reviews are enthusiastic.
"Adobe Edge Animate: The Missing Manual" by Chris Grover (O'Reilly, Nov 2012). I purchased this book in 2013 and love it. And, using this book as an example, I think it is still valuable, which probably applies to many other Animate titles as well. There are some interface changes and upgraded capabilities in Edge since the Missing Manual came out, but the underlying strategies are still the same IMO. A well written book.
thanks redesign and Ethelwild for the great resources. I'll definitely dig into all!
