As of March 5, 2013, a new arc as been published, a prequel arc. The first book in that arc is The Sun Trail which I read just a week ago.
Before Rusty left his kittypet home...
Before Bluestar ruled ThunderClan...
Before Crookedstar made his fateful promise...
The warrior Clans were born.
Find out how it all came to be in this brand-new arc that reveals the origins of the four Clans. Featuring a new cast of characters, a richly developed world, and a never-before-seen look at the history of the warrior cats, this prologue arc is perfect for existing fans and for those new to the Warriors world.
Contrary to what the synopsis says, I honestly wouldn't recommend reading this before the other arcs because of the spoilers to the plot. I would say that current fans will much enjoy this, and it never faltered from previous set standards of Warriors books.
In Erin Hunters majestic world, these cats possess human emotions. Which makes sense, because it is humans that are reading this, right? Anyway, speaking in a metaphorical way, this book in particular to the rest of the story really examines a lot of right and wrong and what is too far.
Gray Wing is a fantastic protagonist, even with his seriousness. You see his ups, his downs, his moments of obliviousness, and with all of them you feel it in your heart along with him. This journey was not an easy one, either. *SPOILERS* In the beginning of the story, Gray Wing's tribe is dying around him. It hits home finally when his younger sister dies, prompting his leader to send a group of his tribe mates to this other territory to live. Gray Wing does not want to go, but his littermate Clear Sky and sweet heart Turtle Tail are going. The group leaves, but then Gray Wings other brother Jagged Peak goes missing, and Gray Wing ends up on this journey anyway, because Jagged Peak was a silly kit and ran away. Now Gray Wing is there, on the journey, trying to make the best of it when tragedy strikes again, Clear Sky's mate is killed and it's Graywing's fault.
I won't go into too much more detail, but this book was fast paced and sad. It had happy moments, and a lot of hope, especially considering that it is a prequel and I know everything that is going to happen next.
This book was well written for a Middle Grade series, and I am eagerly awaiting further reads.
