Isadora Moon is special because she's different. Her mum is a fairy and her dad is a vampire and she is a bit of both and totally unique! When Isadora discovers a wishing well, the mischievous nymph who lives inside grants her the wish of constant happiness. But being happy all the time isn't quite as enjoyable as Isadora expects. Can Isadora convince the nymph to undo the wish, and allow her to feel all of her feelings again? A funny and heartwarming story that gently explores how feelings aren't ' good' or ' bad', and that experiencing all of your feelings is part of what makes you human (or half vampire half fairy!).
