By Erin Hunter
Animals: 10 (well obviously)
There are four series of books. The one shown is the first book in the New Prophesy series. There's also the Original, The Power of 3 and the Omen of the Stars series. I've read almost all of the books in two of the series.
These books are about 4 clans of wild cats, Thunder Clan, Shadow Clan, Wind Clan and River Clan and their starry ancestors Star Clan. They are really good adventures with a bit of magic. They call humans two legs and cars two leg monsters.
I really, really love these books and they would be good for big cat fans like me.
Erin Hunter has also written a series of books about dogs (Survivors) and bears (Seekers)
