'In the land of Cymria, humans and griffins rule side by side ...
Arren Cardockson is a despised Northener, a people conquered and enslaved centuries ago. By freak chance, he became a griffiner - chosen by a griffin as their companion - but many resent and fear his existence.
Meanwhile, chained in a cage behind the fighting Arena where rogue griffins entertain the crowds, the mysterious black griffin dreams of escape. Arren's meeting with this renegade griffin sets his life on an inexorable path of murder, conflict ... and an encounter with his past.
'Darkness cannot be caged.' (From the publisher's website.)
'Arren Cardockson is dead... but something won't let him rest.
Hated and hunted, Arren's only ally is Skandar, the monstrous man-eating dark griffin. Together they must reach the cold North, where they may be able to hide from Erian, vengeful son of the murdered Lord Rannagon.
Then Arren meets the ferocious and mysterious Skade, and he begins to believe that she might know the way to lift his curse and make his dead heart beat again.
And all the while, the dark Night God is watching...' (Publisher's blurb)
