What’s my next read

I’m almost done with Onyx Storm (fourth wing book 3) and I keep going back and forth if I should go straight into threshing day, or take a quick break to read pet Semetary which I recently got first since it’s properly spooky season. I need others to help with what they would do. Go into the next book, and maybe finish to still get pet Semetary in, sooner to Halloween? Or jump to pet Semetary first to ensure I’ve read it before Halloween as passed, and then go back to fourth wing with Threshing Day?
