I read this as Secrets of the Mist
Maddie finds herself in a small Dorset village and is drawn to an old cottage which she buys. After moving in she hears and sees unexplainable things and is then on a mission to discover the history of her cottage and village. A lovely time slip novel with an enticing cover. I loved the story from start to finish, the wonderful descriptions of Dorset make the book worth reading on its own. Just one niggle - too many mentions of feeding the cat! This is the first book I’ve read by this author and will definitely read others by her.
