I need YA thriller / horror recommendations!!

I prefer YA literature but I feel like I’ve hit a wall in the thriller category. I love Holly Jackson and Maureen Johnson, not a huge fan of Karen McManus or Jennifer Lynn Barnes. Does anyone have some recommendations? I’m also interested in thriller / horror if it doesn’t get too scary. I read one kinda of campy horror book recently and loved it so I thought maybe I should give it a try! Bonus if it’s a series!!
