The Boy, the Mountain, and the Serpent Who Ate the Moon by Caris Avendano Cruz

The town of Santo Cristo is known for two things - their colourful town fiesta capped off with a solemn evening procession, and the dozens of people that have disappeared over the years. When three kids - the headstrong Bayani, his sister Isay, and anxious Aaron - find their way over the other side of a mysterious bridge and to a long-forgotten island of myth, they're faced with monsters, cryptids, and sinister characters. In this land of Night, they must find their way back to their world and keep their light burning bright lest they lose themselves too.
