Sal Murdocca

Magic Tree House is an American children's series written by American author Mary Pope Osborne. The original American series was illustrated by Salvatore Murdocca until 2016, after which AG Ford took over. Other illustrators have been used for foreign-language editions. The series is divided into two groups. The first group consists of Books 1–28, in which Morgan Le Fay sends Jack and Annie Smith, siblings from the fictional small town of Frog Creek, Pennsylvania, on adventures and missions through a magical tree house.
