No one knows for sure where Minerva Mint came from. She just appeared in a London train station one dayâ 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, her two new friends, Thomasina and Ravi, have turned the mystery of finding her identity into a wonderful adventure.

The people of Pembrose have long believed that King Arthur and the sorcerer Merlin once lived near their small town. In fact, the cave where Merlin did his magic is a popular attraction for visitors. But now a handsome archeologist has come to town claiming that the cave is just a hoax, a legend to attract tourists. Minerva, Ravi, and Thomasina believe in the legend and in Merlin. Once they prove it to the scientist, the three friends can get back to the mystery of Minerva's missing parents.

The mystery of Minerva's parents is pushed aside once again when the ghost of old Black Bart, a cruel pirate, wreaks havoc in the village of Pembrose. Legend has it that the old pirate was so mean during his life that his spirit cannot find peace until he performs a good deed. Minerva is certain that she can convince Bart to do just that, but first she and her friends have to find him. Will the search for Black Bart's spirit lead Minerva and her friends into danger?

Those who venture into the dark woods never return. But that won't stop Minerva and her friend from heading into the forest - the Order of the Owls never abandons someone in need! But are there some dangers too great for even the brave trio?

The Order of the Owls set sail on a new adventure to protect a nest of turtle eggs from a suspicious thief.
