4.5 stars rounded up. This is my first YA/new adult SF book and it was such a good time. This book touches on race, gender, sexuality, religion, family dynamics, mental health but it is just part of their lives, not a central theme of the story.

It's half character driven and half plot driven. We learn about this group of characters while on their mission to Terra-Two. I loved learning about them and seeing them change slightly (I think the book spans over a just a couple of years for the most part) and also loved the thrill of the mission and everything that happened along the way (I might have even shed a tear, ew). There were a couple of twists I wasn't expecting which is rare for me, an overall very fun ride.
