"I have been watching you for a while now, my love" he whispered darkly in my ear. "Why are you doing this to me" I squeaked, earning a low chuckle from him. "Because" he said, moving his hands from the wall above my head and down my body, resting very low on my waist.

"Listen to me, princess. I've had enough of your attitude. We're both in hell here. So either suck it up or shut up. Do I make myself clear?" -- Emma Winston never expected her father to become President of the United States. When she got accepted into her dream school she never expected to have a secret service agent assigned to her 24/7. And when she meets Harry Styles, her personal 24/7 agent, she never expected she could hate someone so much. Will Harry and Emma learn to silently and spitefully coexist, or will circumstances they never could have anticipated change everything they thought about each other? HIGHEST RANK #1 IN FANFICTION Reviews: "24/7 a very lovely book. It's one of my favourite stories ever! It's really well written and soooo cute. I get so damn excited when it has a new chapter. You always get surprised bc there is often something you don't expect to happen. It's perfect♥️" - @FantaStyles "24/7 is worth the read for anyone, not just Harry stans. It's not predictable or cliche like the title may suggest to some. The amount of times I've gotten whiplash from the characters and the situations is uncountable. The storyline is well thought out and the character development is amazing. This book is an 11/10." - @takemyeverybreath "24/7 is far from the cliche fanfiction it might seem. It's a bodyguard story deluxe with plenty of action (and not just the sexy kind). The characters are well written three dimensional people who really grow on you as you keep reading more and more chapters. There is plenty of drama going on, but unlike you often see, it isn't drama for the sake of drama. The plot is very well constructed and the cliffhangers will certainly keep you on the edge of your seat and checking the Wattpad app or site more often then you might like to admit for updates." - @SophiaGordons
