I Found This in M's Backpack

Dear Mary Pope Osborne (the author of the series she is reading- she is on book 26!),
I M D. (she wrote her name and just her initial) wait stop right there. You are gonna be weirded out but I want you to stop writing your books. P.S. I mean the Magic Tree House Books. signed your friend and fan. PPS Please write back to me

When I asked her why she wanted to her stop, she told me she wanted to catch up (there are 46 of them) before the author continued writing. I wonder if Mary will listen.
