1. Click here (note, this is an epub file, and for some reason, internet explorer doesn't place nicely with it. Try downloading it using another browser, like firefox or chrome)
2. Click the down arrow on the save button and select "save as". Save the file somewhere you will remember it (I recommend your desktop so you can see it)
3. Plug your Nook into your computer via USB
4. Open your Nook through My Computer
5. Drag and drop the file (94604838.epub) onto the Nook (in "My Documents", or at the root)
6. Eject your Nook, turn it on, and the file should be there! Voila!
