I received the "Oracle Coherence 3.5" book in ebook format from Packt. I have been going through the ebook and I am really amazed with it. It is definitely a great guide for both experienced users and newbies. It is extremely well structured, and it's easy to read and understand. Additionally, the book contains a lot of useful information, including basic and advanced concepts, best practices, very useful tips and very good examples too.

In summary, if you want to become a Coherence expert, even if you are a Coherence newbie, this book is the way to go!
