Ambassador, you are go for launch in T- minus 5…4…3…2…. Get ready to blast off with this high-action, high-stakes middle grade adventure that’s perfect for fans of Chris Grabenstein and Peter Lerangis!

Miranda Regent can’t believe she was just chosen as one of six kids from around the world to train for the first ever mission to Mars. But as soon as the official announcement is made, she begins receiving anonymous threatening messages…and when the training base is attacked, it looks like Miranda is the intended target. Now the entire mission—and everyone’s lives—are at risk. And Miranda may be the only one who can save them.

The Martian meets The Goonies in this out-of-this-world middle grade debut where the stakes couldn’t be higher.

Editorial Reviews

“With fleshed-out characters who are intelligent but act like preteens and teens, Slivensky’s action-packed narrative is about grappling with passions, insecurity, and questions of trust.”
