The Oracle's prophecy has come true - the revelations about Pasiphae have blackened Jason's heart, and he bears little resemblance to the man we know and love. His attitude is reckless and foolhardy, and he no longer seems to care about anyone or anything - even Ariadne.

Desperate to save his friend, Pythagoras sets off in search of help. But he soon discovers that not everyone is as keen to protect Jason as he is...

Jason is determined to rescue his fellow prisoners from the amphitheatre. But this means returning to Atlantis, the heart of Pasiphae's power and, with traitors at every turn, this is more dangerous than ever.

As events come to a head it becomes clear that while Pasiphae lives, there will never be peace. For Jason and his friends only one thing is certain - the Queen must die.

As Jason and Ariadne prepare to return to power in Atlantis, they must decide who they can trust. Anxieties run high as our heroes form new alliances with old enemies, whilst questioning those they love.

As they enter the city for the first time since Pasiphae's death, only one thing is certain - nothing will ever be the same again.
