An enjoyable tale
I like Catie as a character very much and was very pleased this novel at least focused on personal merit, equality and stopped the repeated political knocks toward half the USA. (ie the war mongering, outrageous, Trump like president presented in the earlier novels, which is funny as Trump was the only president not to start new wars, though yes his personality is abrasive and needs to stop the tweets).
Anyway earlier novels always felt like CNN lecturing me with references and snubs, when all Americans who aren't polarized simply want equality for all and be left alone and able to prosper. So I was very happy this series who's characters I enjoy returned to a more sci-fi, humanity putting it's best forward and growing together while facing challenges tale, the alt history of seeded lost colonies was very enjoyable.
