Amber's new book The Witches of Echo Park comes out on January 6th 2015, and you may get it from these places:
Barnes and Noble US
There are also some other US links available at the book's Tumblr here. Amber is on Twitter, so you should go follow her. Huge thanks to Amber for being so cool and willing to talk process - we met at LeakyCon, so it was lovely of her to find time to do this. And I didn't accidentally call her Tara even *once*!
I have a few other participants on my list, but if there are any writers you'd like me to talk to - that I might reasonably be able to get - I will gratefully steal your suggestions and pretend I thought of them.
