Young children and seniors alike will have the chance to delve into the fantastical, imaginative world of Mary Pope Osborne, author of best-selling children's book series in Magic Tree House:The Musical Sunday.

"The musical is a big, Broadway style show with 20 huge puppets, dragons that are two stories high, fairy dancers and songs," Osborne said. "It's a spectacle and it's for all ages -- from 4-year-olds to elders."

Magic Tree House: The Musical will be showcased at 3 p.m. Sunday in Eisenhower Auditorium. Tickets will be available at the door and are $15 for University Park students, $29 for adults and $19 for those 18 and younger.

Kim Sivulka (sophomore-French) used to read the Magic Tree House books when she was a child. She said the musical could be a big hit for young readers.

"Especially for children, sometimes things are best left to the imagination," Sivulka said. "When books become movies and shows it kind of ruins it -- but this musical could be a really good thing."

Laura Sullivan, director of marketing and communications at the Center for the Performing Arts, said the performance will be for the whole family.

The musical stars siblings Jack and Annie as they go back in time to the days of King Arthur. It has a Camelot theme, Sullivan said.

Osborne said the musical is loosely based on the book, Christmas in Camelot. Although it may seem youthful in its plot, she said adults can relate.

Jack and Annie are the only children characters, but their adventure seems more grown-up, Osborne said.

Osborne said she remembers how she first became in touch with her vivid imagination.

"I grew up traveling because I was an Army kid," Osborne said. "I love learning about other places. Also, I was very connected with my siblings as a child."

She said when she became an adult, she never wanted to lose her sense of creativity or settle down.

Osborne added she has always shied away from TV and film offers for the series because she wanted the readings to take place in the children's imaginations. She said she agreed to a musical because of her background in theater.

"Theater is as an ancient way of story-telling as books are," Osborne said. "The musical turned into something that was greater than the books and it's been a great joy."

She said she has been the sole supportive voice for the creation of the musical.

"I was strictly a cheerleader," Osborne said. "They would present the songs and I would either laugh or cry."

Some fans of the books have experienced the musical version, Osborne said. The tour started in Connecticut, where many of the cast members' families lived and there was a lot of support from the community, she added.
