The Order of the Owls — Elisa Puricelli Guerra

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, her two new friends, Thomasina and Ravi, have turned the mystery of finding her identity into a wonderful adventure.
