Muncaster, Harriet. Isadora Moon

"Isadora Moon is special because she's different. Her mum is a fairy, her dad is a vampire, and she's a bit of both. When a new girl, Ava, joins her class, Isadora is keen to make friends. But Ava's not interested. She'd much rather be back at her old school, with her old friends, who are much more fun to play with. Isadora's classmates are happy to leave Ava on her own since she clearly doesn't like them, but Isadora figures out that there's something more going on beneath Ava's unfriendly surface. Can Isadora help Ava to let her guard down, and give her new school a chance? A magical story about the power of kindness, inclusivity, and friendship."--Publisher's description
