Most of you probably know this already, but just in case you didn't: You can now buy the Harry Potter e-books directly from Amazon, without needing to go through Pottermore. While you were able to read them via Kindle unlimited, actually buying them from Amazon wasn't possible. But sometime earlier this month, both the audible editions and the Kindle editions went up for sale. I did buy them from Pottermore, but I bet I end up rebuying the Kindle editions, just for the extra stuff Kindle adds (and to avoid having to deal with the differences between native Kindle and Kindle documents). You can find the e-books here.
As the title says, Swords of Good Men is on sale in the Kindle store (US) for $1.99. Its the first book in the Valhalla Saga, with the final book in the trilogy due out on January 5. I liked this first book well enough, but found the 2nd one too grim and unhappy..so I dropped the series halfway though book 2.
Just in case you want to do some last minute shopping for yourself, below is a list of Kindle book deals. Double check the price before buying, just in case they change by the time you see this.
