The Blue House Passage
Warning This Section Does Contain Spoilers
After much research, it was determined that this is not an actual published book. This must be one made specifically for this package and case. This "book" passage shows some parallel to the characters in our case. Emilie is bed-ridden and not able to leave the house, much like Isabella is home bound and not supposed to interact with society as per Granny's wishes. Gwen is the popular, friendly companion that comes to visit, much like Kayla. We may glean more information on this book passage with months to come.
