Thanks! I might be able to offer sketch cards in exchange for people buying books...
That would be great! I've ordered my copies.
Congrats again on your successful series! My secretary's grandkids are anxiously awaiting this, as am I.
Update 2/12/18 - Received my order, and thought it was another great book, both story and illustrations. My mom's reading it now, and enjoying it. Tomorrow I'll give my secretary her copy, so I hope to have reviews from young readers in the near future.
Is "Do Not Open" in a second printing? Hope so!
