The Final Fablehaven

I forgot to mention in my last post that the fifth and final book in the Fablehaven series by Brandon Mull will be coming out on March 23rd of 2010.  It's title will be Fablehaven: Keys to the Demon Prison.  Mr. Mull also said that he will be writing an additional series after Fablehaven (which he has already finished writing, by the way).  I believe (though I can't remember exactly) that the series name is The Beholders and that expects it to be at least as successful as Fablehaven which was, after all, compared to Harry Potter.  In any case, I eagerly anticipate Mr. Mull's forthcoming works!
