YA Fantasy? Main character (girl) is hiding/ on the run from the past. They killed her friend who was sleeping in MC's bed

[Natalie Trojakova]

I actually did not read the book, just heard about it and want to read it, I think the book is quite new and is YA fantasy.
Main character (girl) is hiding/running from her past. But SOMEONE(?) seems to always find her. She told the truth to only one person but he is dead now because of her. They even killed her friend because she was sleeping in MC's bed and they thought it was her. MC says that everyone is lying to her.

Sorry but I dont know anything else.
