three books
Brandon Sanderson said that it is going to be a 'trilogy of a trilogies'. The second sequel is set in an urban setting with modern technology. However The Alloy of Law is a stand alone short novel, not the start of the second sequel.
The new series happens many years after the original, and it does have a steampunk feel to it.
In the first series there are Seven books, however there are 2 or more books in the second series that I know of. The first two are Phoenix and Lion
You could have googled this, but from what i have found there are 2 series. In the first there are 30 books, and in the second there are 19.
There are a total of 5 books in the second series of The Clique: "Charmed and Dangerous," "The Rise of the Pretty Committee," "Boys R Us," "These Boots Are Made for Stalking," and "My Little Phony."
the answer is six. all warriors series has six books, not counting the the field guides and super editions.
There are seven in the first series, however the second series is still being published.
Mistborn: The Final Empire 541 pages, in hardback.
I think there's going to be around 5 books since the last series was 5.
There are seven books, unless you include the second series which are the A La Mode books. So there are 9 altogether.
Seven unless you include the sequel series Tokyo Mew Mew A La Mode which is two books... So about nine books including the second series.
There are two: EON which is the first, and then the second EONA.
