Theodora Hendrix y la Monstruosa Liga de los Monstruos

The first rule of the Monster League of Monsters is: keep monsters hidden from humans. But when the zombie Georgie and Bandido, his inseparable cat, find an abandoned baby, they cannot leave him to his fate since he would be eaten by goblins. So they take the little girl home, where he quickly becomes part of the family. Ten years have passed since that day, and young Theodora does not seem to live in fear even though she was raised by monsters. But now, a series of anonymous letters suggest that someone is about to reveal the secret. If Theodora doesn't act quickly, she could lose her family forever...
