So, I stumbled over something relevant to our Crusaders and incredibly interesting on Equestria Daily last week.....
Next year, Hasbro will release two Cutie Mark Crusaders books! But not just any books about them, mystery books!
Here is the description:

My Little Pony: Mystery Series Book #1 and #2

Join the Cutie Mark Crusaders—Sweetie Belle, Apple Bloom, and Scootaloo—as they read mysteries, legends, ghost stories, and every other kind of tale that makes a mane stand on end. From Ponyville School classmates to Rainbow Dash to the Princess of the Night herself, you never know who else...or what else...awaits. Ideal for younger and more reluctant readers, this new original series complements our existing chapter book program with numbered titles, shorter page counts, and a perennial popular genre. These spooky stories are sure to appeal to all My Little Pony fans—both girl and boy.

It is apparently a whole series of books and so far, two books are planned for it! The first one gets released on April 4th, Volume #2 on July 3rd.
Each book will have 96 pages and be available for a price of only $5.99!

This is incredible news! Hasbro barely releases merchandise and toys for them and they have never gotten any books by G.M. Berrow so far, but now they will finally get some books, after four years! And books with horror stories no less!
I'm excited for this, we're probably getting to hear more dark legends from Equestria!

What do you expect from the books or hope for to see in them exactly?

5629206 Hmm, I hope to see the CMC solve a mystery of some sort, or prove that ghost stories are not always what they're cracked up to be, or maybe learn from Princess Luna that you need to face your fears, real or imaginary, just like in Sleepless in Ponyville.

Interesting

5629206 This has the potential to be really good, it's about time the tie in books included the CMC. Alongside Spike they've been long overdo.

I love the possibilities that this brings. I hope we hear about the Pony of Shadows again and maybe what's true about the legend and what not.
And the Headless Horse! That one especially!

^ THIS. This was a massive neglection by Hasbro so far. Time to get it rectified!

5633602 Yes, I'd love to see the Headless Horse again! It was one of my favorite dark legends of Equestria!

Come to think of it, we never actually heard the story about the Headless Horse that Rainbow Dash was telling during the camping trip.
Maybe we will finally do next year.

5634716 One can only hope. You know, fun fact, I made a story with the Headless Horse as the main villain called "Frightmare Night" a while back. I can send you the link to it if you're interested.
