What is this book called?

Once I read a really good book and I was trying to think of the title to find the second of the series but I can't remember what it was called. It was about a young girl that gets put into a psycho ward type house because she was seeing ghosts, there she meets two boys who help her discover that she is a necromancer an one of the boys is a sorcerer and one is a werewolf, she also makes a friend that is a half demon. They all discover that the psycho ward is a place where they study the supernaturals and they try to escape but the government is after them. Does anyone know what this book is called I've read so many lately Im getting confused and forgetful haha
