Who would want to have tea with mushrooms, when it's a hundred degrees and humid out? As thirteen-year-olds Shelby and Shauna Kitt find out, quite a few people. These are, of course, people from Miriax, a planet in an alternate dimension where nothing and no one is anything like what the brother-and-sister twins expect. On Miriax, lilac tea is served with explosive mushrooms, agitex leaves cure motion sickness, stick insects patrol the jungle, and library books carefully choose their readers, refusing to leave the shelf for anyone else. And, if you're not careful, the walls spit on you. 

Shelby and Shauna's lives change drastically when Miriax recruits them to seal a dimensional hole that allows Klodians -- nasty, nasty aliens -- to travel to Earth. In order to succeed in their mission, Shelby and Shauna discover skills they never thought they possessed, make friends they never expected to have, and face enemies they never imagined existed.
