The final scene is Livys father comes back from the dead and needs her to remember where files are that she has had since she was a child. He dad tries to kill her but the boyfriend turns up. Livy starts to remember her past and they end up married,

Can anyone help??

When did you read it?
Or when was it published?
Author's gender?
Cover?

You also said this about the book. "The first is about a girl, Olivia,who loses both her parents in a car accident and her memory. Years later she runs into her childhood friend who owns a security company and they fall in love. There is more than one book. I’m sure the guys name is Andrew."

I read it about 2 years ago but it wasn't a new book. Yes his name was Andrew and I think there was 2 possibly 3 books.

Can't remember anything about the cover or the author, sorry.

A Beautiful Mess maybe?

Ayshe, Thank you so much!!!!
