In the fourth Jack and Jenny adventure, the Carlton twins are anxiously awaiting the arrival of their friends, Ru and Jin Chen, from Hong Kong. The four friends were in for an exciting time of fun and revelation. They would explore an old mining town, take horseback excursions and encounter a cantankerous old hermit who lived high on the mountain with a vicious dog. Jack, Jenny, Jin, and Ru would also learn that God often had plans that we might rather avoid. It was what God said that mattered, yet this would be a hard lesson to learn. Bravery, endurance, and trust would all play a huge role in whether they accepted God's ways or attempted to live life on their own.
