Minerva, Ravi and Thomasina are certain that the gold key they found at Lizard Manor will grant them access to the legendary City of Ravagers, the long-ago home of a group of fierce pirates. Will the city also shed light on the secret of Minerva's mysterious past?
No one knows for sure where Minerva Mint came from. She just appeared in a London train station one day -- a baby in a bag. Since then she's been living with Mrs. Flopps, the woman who found her, in a rundown mansion called Lizard Manor. It's been nine years now, and Minerva is no closer to finding her parents. Fortunately, she has made two new friends, Thomasina and Ravi, who turn the mystery of finding her identity into a wonderful adventure.
The people of Pembrose have long believed that King Arthur and the wizard Merlin once lived near their small town. In fact, the cave where Merlin did his magic is a popular attraction for visitors. Minerva, Ravi, and Thomasina believe in the legend and in Merlin.
