By Midnight by Mia James

What's on the back of the book:
April Dunne is not impressed.

She's had to move from Edinburgh to Highgate, London, with her parents. She's left her friends - and her entire life - behind. She has to start at a new school and, worst of all, now she's stuck in a creepy old dump of a house which doesn't even have proper mobile phone reception.

Ravenwood is a prestigious academy for gifted (financially or academically) students - and the only school where her parents could find her a place in the middle of term, in the middle of London, on incredibly short notice. So she's stuck with the super-rich, and the super-smart . . . and trying to fit in, when the rest of the students seem to be more glamorous, smarter, or more talented than she is, is more than tough. It's intimidating and isolating, even when she finds a friend in the conspiracy-theorist Caro Jackson - and perhaps finds something more than friendship in the gorgeous, mysterious Gabriel Swift.

But there's more going on at Ravenwood than meets the eye. Practical jokes on new students are normal, but when Gabriel saves her from . . . something . . . in Highgate Cemetery, and then she discovers that a murder took place just yards away from where she had been standing, April has to wonder if something more sinister is going on.

. . . and whether or not she's going to live through it . . .

A piece from the book:
April was boiling with anger as she strode down the corridor. That witch! How dare she? Aren't teachers supposed to help you with problems, not take the mickey? I should report that smarmy cow.
'Hi, April.' She turned to see Sara Gold, a minor member of the Faces, the one Davina had supposedly seen enter a bathroom with Gabriel. She was standing with Layla and they both seemed to be highly amused about something.
'Oh, uh, hi,' said April distractedly as she hurried on.
'Have a good time at the party?' called Sara to sounds of laughter.
April stopped and turned to face them. 'Yes, it was fun,' she said.
'That's what we heard,' said Sara, a touch of spite in her voice. 'A lot of fun.'
'I'm sorry? What are you saying?' said April with creeping sense of dread.
'Oh, nothing. We just heard how you like to spread the love around.'
Sara cracked up laughing at this and April was disturbed to see that a crowd was gathering around them.
'I could say the same about you, Sara,' said April. 'I heard you spent a lot of time in the bathroom.'
The smile faded from Sara's face. 'Who told you that?'
The double doors to the refectory sprang open and Caro came bowling through. She grabbed April's arm and dragged her back the way she had come. 'We need to talk,' she said from the side of her mouth.
'What? What's going on?'
'No big deal,' said Caro. She hurried April down the corridor and out into the grounds. When they were a decent distance from the building, Caro stopped. 'Someone is spreading a rumour about you and a whole bunch of boys at the party.'
'WHAT?' cried April, horrified. 'You're joking! Tell me you're joking?'
Caro shook her head. 'No, I'm not. I wouldn't make something like that up.'
April could feel her heart hammering. God, I've only been at this horrible school a week and already everyone thinks I'm a slut, she thought in despair. I only wanted to fit in.
