When fifteen year old Mio Yamato furtively sneaks the katana – an ancestral Japanese sword – out of its hiding place in her parent’s attic to help liven up her Christmas party costume, she has no idea of the darkness she is about to unleash on modern day London, or the family secrets that she is going to uncover.

The paralysing paranoia that descends on her before she gets to her friend’s party is her first clue. The vivid and terrifying visions that nearly get her killed are a pretty good warning too.

The giant nine-tailed cat demon that comes after the sword and tries to rip her throat out? Overkill.

Seconds away from becoming kitty-food, Mio is saved by Shinobu, a mysterious warrior boy. But it’s already too late. Mio has ruptured the veil between the mortal realm and the Underworld, and now the gods and monsters of ancient Japan stalk the streets of London, searching for her and the sword.

With the help of her best friend Jack, a fox spirit named Hikaru – and the devoted protection of the betwitchingly familiar Shinobu – Mio attempts to discover the true nature of the sword and its connection to the Yamato family. Because if she doesn’t learn how to control the katana’s incredible powers, she’s in danger of being overwhelmed by them. And if she can’t keep the sword safe from the terrible creatures who want it for their own, she’ll lose not only her own life… but the love of a lifetime.

Old Gods never die…

Or so Athena thought. But then the feathers started sprouting beneath her skin, invading her lungs like a strange cancer, and Hermes showed up with a fever eating away his flesh. So much for living a quiet eternity in perpetual health.

Desperately seeking the cause of their slow, miserable deaths, Athena and Hermes travel the world, gathering allies and discovering enemies both new and old. Their search leads them to Cassandra—an ordinary girl who was once an extraordinary prophetess, protected and loved by a god.

These days, Cassandra doesn’t involve herself in the business of gods—in fact, she doesn’t even know they exist. But she could be the key in a war that is only just beginning.

Because Hera, the queen of the gods, has aligned herself with other of the ancient Olympians, who are killing off rivals in an attempt to prolong their own lives. But these anti-gods have become corrupted in their desperation to survive, horrific caricatures of their former glory. Athena will need every advantage she can get, because immortals don’t just flicker out.

Every one of them dies in their own way. Some choke on feathers. Others become monsters. All of them rage against their last breath.

The Goddess War is about to begin.
