Delirium (Delirium (Quality))

Delirium - Lauren Oliver Interesting concept but I felt like the whole "love is a disease" immediately just jumped to "love is a crime" and there wasn't any backstory in the whole novel that provided any insight. How did this kind of thinking escalate?

I'm reading Pandemonium as soon as I can and I only wish Lauren Oliver would provide more background to it. As i've said, it's very very interesting and has a lot of potential.
