Det här är möjligen Spellbokens ultimata bok
Cassy, Verne & Gus are three gifted students who go to an enchanted school where they learn about magic and how to use it. One day they receive a strange talking book in the mail. The book says his name is UBOS (Ultimate Book of Spells) and together they must journey to the center of the Earth to stop Zarlak. Zarlak is a powerful wizard who is stealing all of Earth's magic so he can ultimately escape his prison, at the center of the earth, into which he was banished after a great battle. This begins a journey of a lifetime for the three students – one they will never forget. They have to juggle school life and fighting the forces of evil with only each other and UBOS for help. UBOS is actually Cassy's great-grandfather in disguise, as proven by several episodes, for example, after witnessing the legendary battle which ended with Zarlack's banishment, UBOS says to Cassy, "Come, my child". just like her great-grandfather. In another episode, UBOS said that Cassandra the seventh helped "m(e) – I mean, your great-grandfather" to Cassy and finally admitting it to Verne whilst not being himself.
