You could try the free book from Microsoft, [Exploring CQRS and Event Sourcing](http://download.microsoft.com/download/e/a/8/ea8c6e1f-01d8-43ba-992b-35cfcaa4fae3/cqrs_journey_guide.pdf).

You might also try Greg Young’s [Versioning in an Event Sourced System](https://leanpub.com/esversioning/) which is free to read online. Greg [coined the terms](https://www.eventstore.com/blog/event-sourcing-and-cqrs) and was quite a vocal proponent of the pattern/architecture.
