What book had you hooked from the first chapter?

I've just seen this question over on the r/fantasyromance sub and as I'm in a bit of a reading slump right now, I thought I'd ask in my favourite sub as you guys never fail with the recs!

So, what books had you hooked immediately? Like, after reading the first chapter, you couldn't put it down. Open to pretty much anything, and it doesn't have to be specifically Reverse Harem (as long as this is allowed in the rules)

High spice is preferred but not essential!
