Requiem by Lauren Oliver

This book was a little bit of a slow starter for me, mostly because I couldn't remember what had happened in the first two books. Once I figured that out, things went much better. As Lena copes with the aches, pains, and irrationality of love, she and the rest of her small group find that the Regulators have started patrolling the Wilds. They move towards Portland. Interspersed with Lena's story, Hana's story gets its own sections: Hana is about to marry the mayor of Portland, but everything's not domestic bliss (despite her procedure). I enjoyed the book, but it wouldn't be at the top of my YA recommendations.
