The Perfect Girlfriend by Karen Hamilton

What a bunny boiler of a book!
Nate finished with Juliette six months ago after a whirlwind romance that she thought would be forever…but Juliette believes they are destined to be together and will go to great lengths to keep him!
Debut author Karen Hamilton creates an suitably uncomfortable atmosphere in this tale of the delusional main character Juliette whose single-minded actions become increasingly bizarre even as the rest of her life begins to crumble around her.
A sound four stars.
