Landfall and Revolution are books 1 and 2 in the Ships Series by Jerry Aubrin. The two main protagonists, Zax and Kalare, are growing up in an Enders Game type culture where credits and demerits determine their future. They will either climb the ranks of the military crew of the giant asteroidal ship they live on or they will be frozen to be pooped out on a maybe human compatible world as colonists.
No one in this culture wants to be poop. I found the storyline to be very entertaining. This would make for a good tween to teen series as there is some violence and mature decision making. The editing could use another pass. Three out of five stars awarded.
