Seekers can be read by kids who are somewhere between 9-12 years old. I'm not saying that people who are below or over that can't read it (the series are awesome) but that it just the average age of people who read Seekers.
THere is no fourth book. The series of Seekers is composed of three books.
OK, I looked up tons of interviews of Erin Hunter talking about the Seekers series, and she said something like, "Yes, there will be a 2nd series, and it will be called Return to the Wild." Which means that there will be a 7th, but it will be the 1st of the 2nd series.
The first book in the Seekers series by Erin Hunter is called "The Quest Begins." It follows the journey of three bears as they embark on a quest to find a new home.
The title of the sixth Seekers series is Spirits In the Stars.
Not currently--right now she is working on a dog series called Survivors, as well as Warriors (cats) and Seekers (bears)
If there is, then there will be an entirely new series of Seekers, since Erin Hunter (Tui Sutherland, in this case) only writes books in series of six. As of now, it depends on the success of the current series.
The 6th book of the Seekers series, by Erin Hunter, will be released on February 8, 2011.

Yes, in the 2nd book of the series.
Yes, there is! It is called Seekers: Great Bear Lake.
The Riddle
The second series in the Warriors book series is called "The New Prophecy." It follows the journey of the ThunderClan cats after they receive a prophecy that foretells of danger and destruction.
