Every place has a story. He can hear it. London remembers everything. After a mysterious resonance event beneath the city changes his life forever, young electronics technician Elias Vale discovers that objects and places carry echoes of the people who touched them. 

A watch can reveal a stranger's morning. A forgotten object can unlock decades of history. And sometimes, a single touch can give Elias the skills of someone who came before him. 

But every memory has a cost. As Elias struggles to understand his extraordinary new abilities, a mysterious figure known as The Curator emerges from the shadows of London. The city remembers. Now Echo can hear it.
