The book had a great old fashion story about a girl who visits her grandma in France in an old creepy cottage. She only visits France because she doesn't want to stay too far away from Mario. The second she reaches the old cottage she realises that weird things are happening as if supernatural, this is evident through messages behind pictures, and in locked treasure boxes. Later on, she sees a ghost in the bathroom mirror and a more frightening ghost at the window. If I had to say something about this book I would say that adding a more scary aspect would definitely make the story better, as I realised that the ghosts weren't scary enough for me. The book is quite short and could have definitely been one book instead of 3, this is because the book is moderately long and is annoying that you have to read another book straight after to even see what happens after the cliff hangers. I have to say I did like the writing style and picture of letters throughout the storyline as it puts you in the perspective of the main character, being able to read the letters. It also adds some fun storyline.
