No one should have to handle YA all at once. In general, I disagree with the claim that the genre is “getting too dark”—the real world is pretty fucking dark and teenagers have to deal with that just as much as adults do, with fewer resources. But as a cataloger for a public library, I have to see (and read/edit/type) the summary of everything that comes in. And as an empath, it’s pretty hard for me when everyone’s sisters, brothers, parents, and best friends keep being murdered, raped, kidnapped, and otherwise traumatized.
Every other book is an abusive relationship or dystopian hellscape, and in between we have bullshit too-perfect teen romances to cut the trauma with hormones and saccharine “forever love.” I’ve been thinking that I just grew out of YA, but now that I think about it, my disaffection with it began about a year or so into my career working in libraries, and maybe it’s the overexposure that did it.
