WHAT 本 COME BEFORE FIRESTAR'S QUEST?

Okay, so I began the Warriors Series a few weeks ago, and I just finished the main series. I've started the New Prophecy, but halfway into the book I found it boring. So, I was researching online and saw that Firestar's Quest sounded interesting. DO I HAVE TO READ ANY EXTRA 本 BESIDES THE MAIN SERIES FOR IT TO MAKE SENSE??? Thank あなた all! :]
