Digital versions of books are great. You can carry a whole library on any smart device. You can basically look up whatever you need, wherever you might be. So, while I like physical copies, I do have many digital versions as well. In this instance, you can pick up the digital version of the Filly Sized Follies adventure trio for Tails of Equestria.
From the announcement:
Filly Sized Follies is the fifth adventure book in the Tails of Equestria line. This book contains not one, but THREE different stories to play through, perfect for ponies ranging from levels 2-5. All around Equestria there are ponies in need, and only you can help them!
