I like this book because it explains the characters of many Warrior cats. I own it, and enjoy reading it. Whenever I have a question of Warriors, I check the book and understand the series better. I like the Warriors series and I fully recommend it to someone who has not read it yet. The suitable age would be nine or ten. My favourite cat in the nationally bestselling series is Firestar. That book is very well written; all the Clans and everything they've put in it is mostly realistic. It also gives you another idea of cats--highly unpredictable and independent, with a sense of honour no other animal seems to have.
