I picked this up at the school book fair months ago because I always support the book fairs. I just journeyed through with my son. Super exciting adventure for being stuck at home! We loved the puzzles, and he loved using the Ghost-o-matic. The story (told through “primary sources”) is pretty involved, so you can’t just race through. Following the mystery in the text — what happened to Ag, the owner of the journal — kept us reading past when we should have gone to sleep. As other reviews have noted, I too hope to find another story like this soon. It’s fun to share a book of this nature with someone — like an I Spy book. Reminds me of the Skeleton Creek books, only more interactive.
