Update on my Bingo read

My Bingo is filling up. The only squares left are the ones below:

 

Set on Halloween

Set in autumn

Set in space

 

Native American MC / Witches

 

Serial killers

Set in New Orleans

Horror

“Ice”, “Snow” or “Frost” in title

 

I don't think I'll fill the last four, but the first three I hope to fill by the end of December. The middle one - I need either one of the two. I have read one book that fits both, so I need either witches or a Native American MC. I own a used book about a young modern witch - something YA by a new author for me. I think I'll give it a go.

 

Anyone has suggestions for the first three? I want something light and fluffy. Romance is good. Humorous memoirs are good too. (Yes, I'm that fickle.)
