My favorite thing about this series is that it fits nicely as a prequel to Matched. Now I am working on these books separately. (I'm done with Matched and Crossed but I haven't read Reached)
I also am only part way through Prized (book two of the Birthmarked city)
Spoiler! (Ok all book reviews have spoilers including all of mine) Birthmark has a huge motivation behind reproductive assignment matching if you will? Because of inbreeding and the Matched society is measured about everything. Insane calculations. Not a far leap to thing the Enclave in Birthmarked a few hundred years later is the Society in Matched.
