The Curse of MarsPaperback, 1 August 2016

Starr and her family are on their way to Mars to be the first humans to ever visit the red planet. But they're not alone--they're taking a group of space tourists with them. Visiting Mars is hard enough when it's freezing cold, has no oxygen, and is millions of miles from Earth, but then Starr finds out the other kids on board don't speak English.
