Shortly before leaving for vacation, Jack and Annie remembered that they needed to go to the magic tree house to solve a mystery. Morgan said "your aventure is going to the Roman times you need to find this book or it will be lost forever""WOW! I always wanted to go to the Roman times this will be fun Annie" said Jack.
The magic tree house takes them to the seaside town of Pompeii during Roman times, which was 2,000 years ago. Many Romans traveled to Pompeii for vacation. They built large houses called villas and planted groves of olive trees on the slopes of a nearby mountain called Mount Vesuvius.
As they walked into the town of Pompeii, they noticed there were no birds and the stream under the bridge was dried up. Once in Pompeii, a soothsayer said "go home". Jack and Annie walked by the town forum, public baths and the Temple of Jupiter while looking for the library.
When they get to the library, they start looking for the book "Vir Fortissinus in Mundo". After finding the book, Jack opened the door and noticed everything crashing down in front of them. The ground started to shake as Mount Vesuvius erupted into a deadly volcano. "That is what the soothsayer meant" said Jack.
Jack and Annie ran from the library and headed back to the tree house. As they ran, a great cloud of pumice, ash, and burning rock formed over the city. When it rained down on Pompeii,it coverd the town. They used pillows to cover their heads from the falling ash.
The tree house was in the olive grove on the side of the mountain. Jack and Annie were running towards the volcano while everyone else was running away from it. When they got to the dried-up stream, the brige. They were trapped in the pumice, when a big, strong man named Hercules saved them. He pulled them from the pumice and took them to the other side of the stream.
Jack and Annie made it to the magic tree house, which took them back home. Morgan made them Master Librarians and they went on vacation with their family.
