Probably Magic: The Seventh Magic Marble is book 3 in the Probably Magic Series by Jo Jewell
Otis Smoot, known as Mr. Magnificent, Master of Fire, wanted to be counted among the legends of illusion. Sadly, he always fell just a little short of greatness. Then one fateful night during a show, a most unthinkable tragedy occurred.
Probably and Wally must help find the Seventh Magic Marble for Mr. Magnificent before Brendore, Demon Overlord of the Underworld. It’s power so great, there would be no stopping Brendore’s path to destruction.
Probably must travel into the Spirit World. A world full of creatures hungry for the living, creatures that inhabit nightmares and go bump in the night.
When she realizes the souls lost that fateful night are being held captive by Brendore, the stakes become higher and the race against time becomes a life or death marathon.
