This is technically the second book in this series, but I’m starting to get the feeling the author pulled apart one (maybe two – the series is young) books to make more parts.
In the last book, Jess and her brother were among the crew of a Mars ship sent to Earth to get the food they need to survive. Officially, there’s no one on Mars – they’ve been considered dead by Earth for years, but there have black market support back on Earth. Their mission went terribly wrong, and only Jess and the mechanic make it back to Mars. In this book, Jess pretty much steals the ship almost as soon as they get back, and returns to Earth. That’s it.
Yes, there’s a some action on Earth where her brother Ethan is getting used to his new body (long backstory), and other things happens (with characters you won’t understand unless you’ve read book one). That’s why this seems very incomplete to me – the whole book is a transition act. I can’t even say it’s good or bad- it just is.
