Warrior Cats: Forest of Secrets by Erin Hunter

the third book in the Warrior Cats original series

Warrior Cats: Forest of Secrets was an amazing book. In Forest of Secrets there is so much suspense. It turns out that Graystripe, a cat loyal to Thunderclan is sneaking out to see a cat called, Silverstream, who is apart of Riverclan. Cloudkit, who is Fireheart's sister's kit, becomes an apprentice. Also at the gathering all the other clans find out that Thunderclan is holding Brokentail in their camp. Fireheart is the mentor for Cloudkit and he takes him hunting one day and they both see Tigerclaw meeting other cats, rogue cats, and he starts approaching the camp to attack it and Tigerclaw himself going to kill Bluestar, who only has about one life left  of the nine lives she has that was awarded to her by Starclan when she became leader and ventured to the moonstone. Also Fireheart finds out that Bluestar mated with Oakheart when they were younger and she was going to be the Leader of Thunderclan so she couldn't have kits. Oakheart was a member of Riverclan. In the end Bluestar does not die and they banish Tigerclaw from Thunderclan territory and community. Before moonhigh Bluestar called a meeting to choose a new deputy since Tigerclaw was the deputy and now he isn't. She picked Fireheart to be the new Deputy; isn't that a great ending.
