Awesome. Hopefully within a month or two.

Yeah---each chapter begins with background on the chapter's topic, some theory, covers how and where you'd use what's we're talking about in the chapter and then we use it to build a part of the project we're building throughout the book. For example, in the consensus chapter we talk about what problems it solves and how you can use it in your projects,and then we implement Raft in the service for leader election and replication.

Not sure, haven't gotten to that yet. Just from looking at the prices of other PragProg books somewhere around $21.95-24.95.
