Dimensions In Time — Lawrence Johnson

Michael and Eddie thought that the worst was over when their Uncle Joe passed away. It was embarrassing having to listen to him talk about Gnomes, Fairies, and Unicorns as if they were real.

Shortly after Joe's passing Eddie discovers his uncle's odd looking ring and an old map that leads the two brothers on a quest to a secret portal deep inside the Amazon forest. The brothers soon find out that old Uncle Joe wasn't as crazy as everyone thought.
