Strange oil, a secret box, mean girls, and an ugly toad occupy the minds and adventures of best friends Johanna and Kenyeh when they joyfully reunite at Mt. Sinai where Johanna's Hebrew people are living. Together the best friends face mean girls, a bully, and a scary old man while also learning from Moses the way the Hebrews (or Israelites) are to live and worship now that they are freed from slavery. Kenyeh grows in faith in the God of Israel as Grandfather teaches her about Him, while Johanna's faith grows stronger as she sees His power. Both girls look forward to packing up and moving into the land the LORD has given to the Hebrews. Together they dream of good things to come. But first, there is much to learn in the shadow of the great mountain.
