Here is a free, condensed MongoDB ebook. You just have to give some (fake) info and a spam-trap email address, and you can download it. Their "<blank> Succinctly" books are usually pretty good, and fairly short and to the point so you can read them fast.

It also has a few chapters on using MongoDB with .NET (their normal topic), which can be quite useful.

Hey hey hey, guess who wants to learn about MongoDB and wants to get into .NET web-dev? This guy! Will download, thanks for sharing
