Gallowglass by S. J. Morden was our January BuddyRead book.

Jack has it all. As the son of billionaires he has no worries other than his parents trying to force him to get treatments to become immortal. Who wouldn’t want to live an endless life full of riches?

Well, Jack doesn’t. So he comes up with a plan to flee from his parents’ home, from his country, from Earth. He has organised it all in secret. He even has a job ready. But when his parents cross his plans, he’s forced to join the crew of a ship that wants to haul a very large asteroid from the edge of the solar system to lunar orbit. He has the training, but no work experience, and this first job could easily become his last when obstacle upon obstacle unfolds.

The story has an underlying climate change agenda, but it’s so subtle, you need to really look for it. It basically gets swamped by all the trajectory calculations Jack has to perform. I liked the quotes about climate change at the beginning of each chapter though. Some of them were dating back as far as the 17th century, which indicate that the climate change we are facing now was predicted back then already.
