I started off with low expectations, but was pleasantly surprised by the no-nonsense style of writing, that took time off to explain the most important topics

It gets minus-marks for a lot of errors in the code-examples, and the use of Ruby (which you really need to know to appreciate the book, along with JavaScript). But I can still recommend it to anyone that wants to learn MongoDB as a NoSQL-database

Probably one of the best books on the subject at the time of this review.
