I would wait before sending another request since you already sent out two of them 2 months ago.

Hi, I just bought "I know who killed me" and I wonder about sending its cover to Linds {??} its made of some kind of a glossy cardboard or smthing like that ;p I also have "Georgia Rule" cover of the same material. Has any of you guys sent a cover to LL? Did you get it back signed? And won't it look pushy to send it because it would be my 3rd letter to her but I got nothing back yet from previous though I have sent them 'bout 2 months ago
