This is a fairly good introduction to the Eberron campaign setting that's system-neutral, perfect for 5th Edition GMs looking for a beginning framework to run a game in this awesome setting, as well as being a stylish introduction for their players.

My only problem with the book is the authors' strange aversion to compound sentences. The whole book gives off this vibe that it wasn't written by WotC designers, but by one of their 9-year-old children tasked with reading Keith Baker's campaign setting book and writing a book report on it.
