In this daring adventure tale, siblings Rose and Ben search for their missing grandparents, aided only by a lantern, their wits, and a mysterious book of puzzling mystical Jewish stories.

Ben and Rose have received a strange book of stories from their beloved–but missing–Bubbe and Grandpa. The siblings dive into the book searching for clues that will help them find their grandparents. But they are not the only ones searching. Who is the strange creature called the Doughlem who shows up in each of the stories? What are the dark forces that also seem to be searching for the book, and pursuing Ben and Rose? As more and more characters from the book start showing up in real life, Ben and Rose must figure out whether the book is coming to life, or if they are getting lost in the story.
