Theo and Tyler are best friends who love having adventures, and in this book they are certainly not disappointed. Together they discover a sunken pirate ship, find an escaped prisoner in a secret cave and also face the move from primary to secondary school. Both boys are Christians, and their faith helps them to face their difficulties by praying and remembering God's word, even when their lives are in danger. In every instance their prayers are answered in the way that they had hoped, which could lead the reader to believe that this is always the case, but their example is always a good one to instil and reinforce. This is an exciting story which would appeal to 8-12 year old boys and is part of a series of adventures featuring the "Two Ts".
