Moonflower and the Pearl of Paramour (Fairy Chronicles)

Rose is a fairy trapped in a magic painting. Henry is a brownie prince trapped in a magic book. Moonflower is another fairy, and Madam Toad picks her to lead the mission to get them out of the book and painting. The book and painting are in a castle that is half covered in moss and half in roses because that matches Henry and Rose who are not allowed to see each other right now. Moonflower goes to find a Wishing Star first. They wish on it and a unicorn comes to take them to the Goddess of Love who has a magic pearl. It is harder than it looks to get to the castle and break the curse because they have to carry a magic candle, and the candle can't go out not even when it rains. You will know how it all ends when you read it because I am not supposed to give away the ending. It is a very good ending, and I think you will like it.
