Some time ago Packt Publishing has submitted to me the technical review of the book "Activiti Business Process Management 5.x Beginner's Guide."
The link to the book is: http://bit.ly/1kna12U
Now the book is on sale and I recommend it to anyone looking to start learning the basics of Business Process Management and implement them quickly using the open source framework Activiti BPM Platform (http://activiti.org)
