Escape from OtherWorld Island: The Adventures of Rae & Danae (Hardcover) (ISBN-13: 9798988699323)

There's never a dull day when you and your older sister are the world's top teen-scientist-adventurers.

But when your arch-nemesis manages to trap you on a remote tropical island (complete with a volcano about to explode)...Well, that's when things get really interesting.

It's a race against time for Team Rugged Stuff and the inhabitants of the OtherWorld!

Danae and Rachel Rugg's scientific discovery of a brand-new world has been hijacked by their rival, the young evil mastermind Colin Null. The clock is ticking as they try to make their way home and foil his plans before he steals their research for his own and lays claim to the girls' latest invention--a meteor-powered transportation portal--and the new world to which it leads!

Joined by their cousins Noah and Levi (a pair of part-time special agents in their own right) and Colin's sister, Nessa (smart, rich, beautiful and just whose side is she on, anyway?), the sisters of Team Rugged Stuff take on the challenge with their trademark wit and grit that is a celebration of the determination of tough young women everywhere!
