Scarlet and the Kingdom of Gealach by Heather Olson (Paperback)

Scarlet and Joshua are on the hunt again for treasure and adventure, but will this time go as well as the last? Their Captain has found out their secret, and if he doesn’t help them find the location of their next map, they’ll be forced to stop their expedition altogether. Not only that, but this time their map is leading them underwater to a place no one has ever returned from, “The Kingdom of Gealach.” Can they get there and back when no one else has? Will their crew cause their journey to end when it’s barely begun? It will take all of Joshua’s talents, and every ounce of Scarlet’s stubborn determination, but if they can reach their destination, what they seek to find will be worth every piece of gold the world has ever seen.
