Watch Your Back: A nail-biting YA thriller

Keep your friends close and your enemies closer...

Kara is starting the school year without her best friend, Eden — who’s now way too busy with her new boyfriend.

Enter Romilly: a girl from her year with no friends. Kara finds herself drawn to her but the more Kara hangs around with Romilly, the more unsettling things start to happen.

There's the break into her locker... the silent cold calls... and more. But can Kara be sure it's Romilly who is derailing her life?

One thing is for sure. Someone is targeting Kara, and if she doesn't work out why, who knows what they will do next...

A nail-biting teen thriller, perfect for fans of Karen McManus, Natasha Preston, and `We Were Liars´.

Former journalist Sue Wallman, now a secondary school librarian, is an award-winning author and one of the UK's top teen thriller writers. Her debut featured in the WHSmith/Zoella book club.
