All Erin Hunter books in EPUB format. Most of this is originally frombut I threw a couple extras in here for completion purposes. I went through HELL (aka probably around 5 or so hours of searching) to find this, and I made an account just so I could put this on here to save you guys all the time I spent, so you guys better be hella thankful I decided to upload this.

If you don't have an e-Reader, you can probably download Calibre to convert from EPUB to PDF.

Contains:
Original Arc 1-6
The New Prophecy 1-6
Power of Three 1-6
Omen of the Stars 1-6
All 4 Field Guides
5 Super Editions - Bluestar's Prophecy, Firestar's Quest, Skyclan's Destiny, Crookedstar's Promise, Hollyleaf's Story. Sorry no Mistystar's Omen, that book is way too new for me to find.
