ABANDONED. new adult/paranormal (book came out in last 2 yrs) group of boys/girls traded to 2 other planets

[Murrielle]

This book came out in the last year or two. Re-colonized Earth now populating 1 of 3 planets (or 2 planets and a moon). Earth young adults (girls and boys) traded / given to the other 2 planets in payment for re-colonization or for materials. One group is for slaves other to become warriors. Best friends (boy and girl) gets separated to different classes. The girl is given to 2 leaders. The ending is a cliffhanger where the girl escapes trying to get to another zone on the same planet.

The "Slave Trade Trilogy" by Susan Wright sounds similar to your description, but books were published in 2003-2005. The first novel is Slave Trade.
