Songs of the Dead

A London rocker is faced with a life-or-death choice when he realizes that a powerful society of magic wielders are the only ones keeping London safe in this deft contemporary fantasy cowritten by #1 New York Times bestselling author Brandon Sanderson with author and musician Peter Orullian. 

When Jack Solomon, a struggling musician who works in London’s West End, is killed, he awakens to a new reality in which light and music are used to create magic and where living eras of the past sprawl beneath modern London, layer upon layer, all the way back to recorded history.
 
 Jack also soon discovers that many of those who reside in the stratums of London’s past have grown angry with the present world, and that their anger is being channeled by a powerful society of light-and-music-based magic wielders who can cross the realms between life and death, between the present and the past. A past where the dead are sowing revolution against the living, and all of history is at stake.
