Life is your Magnum Opus

Eleanor Davies finds a book titled 'The Story Of your Life' on her bedside table with a cryptic note on top of it. The book has all information about her, filled with every milestone, every happy, sad, embarrassing moments of her life. When she reaches the present time of the book, she realises that only a handful of pages are left. Now, she has to solve the mystery of the book and find the identity of the person who left it for her. I know this is really vague and bad, but a better synopsis will come soon!!
