"After countless moons of treachery, Tigerstar's Dark Forest apprentices are ready to lay siege upon the warrior Clans. As Jayfeather, Dovewing, and Lionblaze prepare to lead their Clanmates into battle, they await the arrival of the mysterious fourth warrior who is prophesied to help lead the Clans to glory." Publisher's description.
This is the last book in the Warriors sub-series "Omen of the Stars." It has a sad ending, which I probably shouldn't spoil, but it leaves a decent cliffhanger, meaning it will probably lead to a fifth sub-series by Erin Hunter. I enjoyed reading it, and if you enjoy books by Erin Hunter, you should definitely read this book.
