Saving Ashley

On Ashley's eighteenth birthday, she got one hell of a surprise. She came home to find a random guy on her bed! The mysterious guy, who no one can see tells Ashley he's going to stay until she isn't alone anymore and in the mean time? Well, he's going to be her best friend!
Here's the thing, he's a ghost. He's made it his mission in his ghost life to make sure that Ashley becomes happy, gets her life on track and starts communicating with others instead of isolating herself from society. He's going to help Ashley and she's going to help him by helping herself... If only she'd just give in easily.
