Well there are no books in the fourth apprentice because the fourth apprentice is a book in the series omen of the stars.
If you mean the Series, Omen of the Stars, So far there is The Fourth Apprentice, Fading Echoes and Night Whispers.
Yes, in "The Fourth Apprentice" by Erin Hunter, Millie and Graystripe's kits—Briarlight, Blossomfall, and Bumblestripe—are all given opportunities to explore relationships and find mates. Blossomfall and Bumblestripe are shown seeking companionship among other cats in the story.
There will be 12 books for Ranger's Apprentice, and there is only 10 out so far. So, there is no way of knowing when all of them will be out.
Well . . . I can give you the plot because there aren't many alliances in the first book. There is a drought. Not much water. Dovepaw is known to be the fourth apprentice. She senses beavers. Cats from all clans help. Leopardstar is ill and on her last life. At the end Jayfeather learns that there will be a battle with StarClan and the Dark Forest . . .
I truthfully don't know why (and I've read all the books three times (on my fourth round) and I read anything about Erin Hunter and there's nothing I've seen about it). I guess it's what she prefers. . . But, to keep updated on the series (even the new one, The Fourth Apprentice), go to thewarriorweb.webs.com (it's my website). You can RP (role play), learn about the books, clans, and leaders, and a lot more! I'm also making a trailer for the Warriors Movie, and I'm making a video game!
The books in the Warriors: Omen of the Stars series are The Fourth Apprentice, Fading Echoes, Night Whispers, Sign of the Moon, The Forgotten Warrior, and The Last Hope.
You can find the descriptions for all warriors books on amazon.com or on the warrior cats official website.
