Amelie Wen Zhao: Song of Silver, Flame like Night

In a fallen kingdom, one girl carries the key to discovering the secrets of her nation's past – and unleashing the demons that sleep at its heart. An epic new fantasy duology inspired by Chinese mythology.
Once, Lan had a different name. Now, she goes by the one the Elantian colonizers gave her. She spends her days scavenging for remnants of the past. For anything that might help her understand the strange mark burned into her arm by her mother, in her last act before she died.
No one can see the mysterious mark – until the night Zen appears at the teahouse and saves her life.
Zen is a practitioner, one of the fabled magicians of the Last Kingdom, whose abilities were rumoured to be drawn from the demons they communed with. Magic believed to be long lost. Magic to be hidden at all costs.
Both Lan and Zen have secrets buried deep within. Fate has connected them, but their destiny remains unwritten. Both hold the power to liberate their land. And both hold the power to destroy the world.
