Finally, the RavenDB in Action book I've been working on for the past couple of months is available in early preview. At the time of this writing we have 4 chapters ready, and more will be released as soon as we are happy with them.
Besides getting content faster to our readers, the early preview release also allows us to receive early feedback from readers and improve chapters as we go, before the book goes to print. And I'm looking forward to getting this feedback.
See more details at Manning's website. The first chapter is also available there for free.
