Night Whispers (Warriors: Omen of the Stars Series #3) Book

If you haven't read the other Omen of the Stars books, don't read this review.

Tension between the clans is rising. The Dark Forest is growing stronger. Cats are betraying their clans every night in their dreams and the battle between the clans and the Place With No Stars is coming closer every day. Ever since the death of the ShadowClan deputy, Ruessetfur, ThunderClan and ShadowClan have been hostile to each other; even to the point of capturing Ivypaw, a ThunderClan apprentice in exchange for life-saving herbs. Ivypaw keeps getting more jealous of her sister Dovepaw so she goes to the Dark Forest in her dreams. Tigerstar tells her that he will train her to be as great as Dovepaw so everyone will notice her and she will help her clan. It's a lie. He just wants her to join the Dark Forest (which is the same as the Place With No Stars) and fight along side them so they can take over the forest. The clans must stand alone now, even though they have relied on each other for as long as the clans have been around. Will Ivypaw still go to the Dark Forest, or can Dovepaw convince her that Tigerstar is just using her? Who will win the final battle between the Dark Forest and the Clans?
I thought "Night Whisperers" was really well written and was really upset when it was over. This book had the most betrayal by far, not only between the clans, but within the clans too. There was danger on every page and it wasn't slow to get into.
