I have absolutely no idea how much I should start this book out at.  In 1992,  I went to a book signing by Ann M. Martin and my sisters.  She signed our books and I am considering putting it on here.  It says "To Katie  -Ann M Martin" and below it is the yellow post it that the assistant wrote "to Katie" on so Ann would know who to make it out to.  It is Mystery  #6 The Mystery at Claudia's House.  Does anyone have any helpful info?  Thank you.
