Who Let the Gods Out:
Elliot's mum is ill and his home is under threat, but a shooting star crashes to earth and changes his life forever. The star is Virgo - a young Zodiac goddess on a mission. But the pair accidentally release Thanatos, a wicked death daemon imprisoned beneath Stonehenge, and must then turn to the old Olympian gods for help.
Simply the Quest:
Elliot Hooper's troubles are far from over: his mum's health worsens, he's struggling at school, and a bunch of anarchic Greek immortals have moved into his home - including teen goddess Virgo, who's in trouble with the Zodiac.
