Gimo Jr and the Aswang Clan by Andrew Jalbuena Pasaporte (paperback)

Danny thought Pinetown was just a boring, quiet suburb. But on his thirteenth birthday, the veil is lifted. Beneath the surface of his ordinary life lies a world of ancient Filipino folklore and a clan of blood-thirsty legends. Danny has just received a "gift" he never asked for--one that could help him solve the town's darkest investigations or plunge it into supernatural chaos. Alongside his best friend Eddie and the sharp-witted Mary, Danny must navigate a world where the monsters of Philippine myth aren't just stories told to keep kids off the streets at night. They're his neighbors.
