What are Aquaterrans and Terraquans doing in England? Why can't Kitty, Sam, Toby, Lizzie, Luke, Jemima, and Jessica contact the Multiversal Research Centre? Why are coffee shops and toy shops being taken over by a mysterious new company? Investigating the company, Kitty's team find out who the joint owners are: two women who shouldn't be there on Earth at all. They'll have to stop them before even more harm is done. How can they do that? Drop the huge energy shield. But that means being in three places at once. To succeed in time, they'll have to overcome sentinels, virtual adventure and educational worlds even weirder than those they've come across before, and outsmart the joint owners of the company.
A fast-paced and thrilling sci-fi adventure for middle-grade readers.
