You'll have to resort to the old way of actually reading books and practising. But If like me you think that's a fun proposition, I'm going to list a few books that I've found to be pretty good for starting your JS quest.
People praise this book for being easy to follow. It's written in a tutorial style, so it makes learning feel a bit like a game. The digital version provides interactive examples and a way to play with the code on your browser, so the experience is very hands-on.

2. Smashing Node.JS - Guillermo Rauch
Every node.js programmer should own this book and their copy should be very used up.
Besides that, this short book will take you through concepts that are at the core of JS mastery. How to use the `new` keyword, how prototypal inheritance works... All useful things to know for your next technical interview.
This book is never far away from me, great as reference and essential in any JS programmers library. It's available from O'Reilly.
4. Node Cookbook - David Mark Clements
There couldn't be a top ten list about technology books without a 'cookbook' style contender. Recipes are a great format for technology books after all - you usually end up referring to the book when you want to remember how to do something, and following a recipe is easy and fun.
It's available from packt publishing.
Due to its nature, it is more of a reference book rather than a teaching tool. It won't tell you how to write a program, or how to use a function, but it will describe in concise detail how the function works. The section about closures is the best explanation available to date.
It's age is showing a little bit, but it still remains the definitive guide. However, at almost 60 dollars, there are cheaper ways to learn JS. It's available from O'Reilly
6. Node.js in Practice (WIP) - Alex Young and Mark Harter
This book hasn't been released yet but it's catching a lot of attention. Their publisher, Manning Publications, has provides an Early Access program, so you can read the parts of the book that have been completed, while the rest is being written.
I haven't had access to it yet, but I'm including it in this list because I keep on hearing about it in #node.js and the few that have read it seem to like it very much. The writer, Alex Young, is an avid JS blogger at DailyJS, and his articles are a great starting point to see if you like his writing style, before you consider buying in on the access program.
The book is available from Manning's website
7. Node.js in Action - Mike Cantelon et. al
This one is good for Ruby and PHP developers that want to start wearing the proverbial skinny jeans of Node.js. After all, Ruby and php are so 2008! With a heavy focus on web development, it covers Connect and express, the most widely used web application frameworks for Node.js.
It's a good all-rounder book, and a great introduction if you know how to build web apps but you feel like you or your tools (PHP and Ruby) are starting to show their age.
It's also available from Manning's website
The book has a section on automated build systems, using Ant, which I think feels a bit outdated. There are tools like Grunt that will do that in a more natural way (at least for JS developers).
It's more of a front end oriented book, but a must have if you're doing JS professionally.
You can buy it from O'Reilly
9. Node Starter - Pedro Teixeira
I particularly like the bit on EventEmmiters, which will save you a lot of trouble when you (undoubtedly) encounter them in the wild.
It's also pretty cheap at about £7 from Packt Publishing
10. Mastering Node.js - TJ Holowaychuck
This isn't a book, more of a very long blog post, but you should definetely read it once you're confident with JS and want to start building big applications. It explains the conventions used in the industry to create reusable modules. Addy Osmani is a great writer and the book is free, so you should definetely read it.
