LOS ANGELES, 2050. A FUTURE STILL TRAPPED IN THE PAST...

For all the mysteries teen hacker Marisa Carneseca has solved, one has always eluded her: when she was two years old, she was in a car accident in which she lost her arm, and a mob boss's wife, Zenaida de Maldonado, lost her life. No one can tell her what she was doing in that car, or how it led to the feud between the Carnescas and the Maldonados.

Even in a world where technology connects everyone's minds, it would seem that some secrets can still remain hidden.

Those secrets rise violently to the surface when Zenaida's freshly severed hand shows up at the scene of a gangland shooting. If Zenaida is--or was-- still alive, it means there's even more about Marisa's past that she doesn't know. And when everyone from Lost Angeles gangs to the world's largest genetic engineering firms becomes involved in the case, it's clear there's more happening under the surface than anyone cares to admit. The truth is out there, and Marisa will have to thread together lost friends, corporate assassins, a gang lord's digital brain, and what might be a literal ghost from the past in order to find it.

Dan Wells's widely acclaimed Mirador series continues with his most shocking, visionary, pulse-pounding story.
