Retells, in graphic novel form, the tale of eight-year-old Jack and his younger sister Annie, who find a magic treehouse which whisks them back to an ancient time zone where they see live dinosaurs.

"You just gotta learn to roll with the punches! When the yetis are kicked out of their humble treehouse abode, it's up to Jo, April, Mal, Molly and Ripley to get them back where they belong amongst the trees...and not leeching the camp's power and making all the ice cream melt. To get the sasquatches to clear out, though, the Roanoke girls will have to challenge them to a roller derby match!"--Page 4 of cover.
