Swarmthief's dance - Deborah Miller

Long ago, there was war in Heaven. Rann, guardian of the Underworld, fought with the Nulefi, and in that battle the Nulefi were defeated. But though their bodies were destroyed, the spirits of the Nulefi remained, and they wander the world of Myr, cloaked in the shattered form of the Swarms, waiting for the moment of their revenge.

Now they have re-awoken, and one human boy, Vivreki, has witnessed that rebirth. The Swarm calls to him, whispers to him the secrets of a vanished age. To Vivreki this seems a miracle, but to his masters it is heresy. For very few now honour the elder gods, and those who still do are wise to keep silent about it.

In fear and peril of his life, Vivreki is hidden away from those that would kill him for his special knowledge. His memory is erased, his past denied, and a new life started for him half a world away. But the Nulefi have not forgotten Vivreki - he alone can hear them, and now he alone can save them. And as the Nulefi struggle to reach their only ally in the world, Herrukal - father of the gods - discerns the rise of a new power on Myr that he will not tolerate.
