I'd really like to get a robust discussion of the great young adult novels that came out in 2018, in advance of the young adult award nominations.  (Yes, I know it's technically not a Hugo, but that's bureaucracy.) Apparently, according to Helen Gbala at the ALA, they already have over 300 titles suggested for the Hal Clement award, which is only science fiction! So, what are the interesting speculative fiction young adult books that you've read this year? ETA: Also welcome here are recommendations for YA-related fan artists, book covers, and professional artists that we think would make great Hugo nominees.
