Each month, Amazon offers up 100 Kindle ebooks for under $4 each from various genres like mystery, fantasy, science fiction, non-fiction, biographies, self-help, romance, and much more. Visit the main Sale page to view all eligible titles.

The most enticing deal on the list is definitely The Chronicles of Narnia: The Voyage of the Dawn Treader Enhanced Edition by C.S. Lewis for only $3.99.

Here’s a few other sale items that caught my interest:

– Rides a Dread Legion Book One of the Demonwar Saga by Raymond E. Feist – $1.99
– Surfing through Hyperspace Understanding Higher Universes in Six Easy Lessons by Clifford A. Pickover – $2.99
– Gandhi’s Passion: The Life and Legacy of Mahatma Gandhi by Stanley Wolpert – $1.99
– The Last Apprentice: Revenge of the Witch by Joseph Delaney – $1.99

I want to point out that $3.99 is an awesome deal for the Enhanced Edition of The Voyage of the Dawn Treader, which I reviewed back in October 2010. It’s got audio and video, as well as the text and the book itself is a wonderful installment in the Narnia saga. Definitely a must-grab in this sale.

Note, these deals are valid only for the month of January 2012 and will expired at the end of this month.

Also of note – you don’t actually need a Kindle device to read these ebooks. Books can be read on Kindle or one of Amazon’s free reading apps for iPhone, iPad, Android, Windows PC, Mac, Blackberry, and Windows Phone 7. Also, you can gift Kindle books and set your gift to be delivered whenever you want to anyone with an email address.
