I liked this book. I wanted to love it. It's not a bad read by any means, but it took too long for anything significant to happen for me. 6 teenagers and 4 vets are on a space mission to a distant planet named Terra-Two. The trip will take them 23 years and requires them to travel out of our solar system. You get a POV off all 6 teens, but the book mainly focuses on 3.  It also focuses on the mental and physical impacts that space travel has on astronauts.  I thought the book was going to focus on their 23 year travel and the significant moments that happen in between, but that was not the case. 

It is beautifully written. The descriptions she uses, and the way the imagery is laid out is magnificent. I would pick up another of Temi Oh's books.
