I looked at all the YA SF nominees in the Locus Awards...

...I went to the Kindle pages and read the opening chapters, just to see. And ALL TEN of them are written in first person POV. This boggles me. A couple decades ago when I was reading a lot of "how to write SF" advice, the most consistent message was "1P is a trap for noobs, don't use it!" Now it is apparently required to get a YA novel nominated. Amazing.
