In San Francisco in the mid 1960s, a cosmic blue light strikes people in its path, quickening their DNA, and greatly enhancing their strengths and understanding. They become the Blues, powerful yet vulnerable. And Blue Light is their story. Narrated by Chance, a half-black, half-white follower of the Blues, the novel traces their desperate conflict with one of their own, a man who - struck by the light at the moment he died - has become the living embodiment of death. Blue Light refracts questions of identity, race and humanity - hallmarks of Walter Mosley's writing - through a gripping adventure that puts a dazzling new spin on the relationship between past, present and future.
