Musty Old Magical Curiosity Shop [EPUB ebook] 

A fantastical children’s story based around the Laugherty family and the adventures they have when visiting the Musty Old Magical Curiosity Shop, which sells anything that anybody wants. "The shopkeeper looked very strange to Miles. He was wearing a pointed purple hat decorated with stars that twinkled like real stars. His eyes were piercing like X-rays. They went right through Miles’s body and made him feel as though the man knew everything from A to Z." Mabble Merlin turns out to be the wildest, wackiest, most wizardly shopkeeper you could ever hope to meet, and everything in his shop is odd and magical.
