One excited little girl!

Izzie has been waiting almost 3 weeks to finally check out the last Magic Tree House book, #47! 

  

Well, it's not truly the last book of the series.  The newest book, #48: A Perfect Time For Pandas was released on July 24, but hasn't arrived at our library.  Yes, we're first on the waiting list to get it!  I just discovered that #49 won't be released until March 2013.  Any suggestions on a new series for us to begin reading?
