Swapping Ancient Greece for Ancient Mesoamerica, Evans' Who Let the Gods Out? series continues with a set of deities. Immortals are at it again, introducing the Gods Squad taking them on. Vesper is the daughter of Elliot Hooper, the original hero of Who Let the Gods Out?, and Aster is the son of Constellation, Virgo. Together, they must recapture villainous wrong'uns before the world ends next Thursday. They head to the Maya underworld, where Kizin and his Lords and Ladies of Death are messing with astronomy, chocolate and human sacrifice. Along with the Gods Squad led by Vesper and Aster, characters from Who Let the Gods Out? return.
