Most cops get to deal with living criminals, but Agent Kirsten Wren is not most cops. A gifted psionic with a troubled past, Kirsten possesses a rare combination of abilities that give her a powerful weapon against spirits. In 2418, rampant violence and corporate warfare have left no shortage of angry wraiths in West City. Most exist as little more than fleeting shadows and eerie whispers in the darkness. Kirsten is shunned by a society that does not understand psionics, feared by those who know what she can do, and alone in a city of millions. Every so often, when a wraith gathers enough strength to become a threat to the living, these same people rely on her to stop it. Unexplained killings by human-like androids known as dolls leave the Division One police baffled, causing them to punt the case to Division Zero. Kirsten, along with her partner Dorian, wind up in the crosshairs of corporate assassins as they attempt to find out who – or what – is behind the random murders before more people die. She tries to hold on to the belief that no one is beyond redemption as she pursues a killer desperate to claim at least one more innocent soul – that might just be hers.

Some soldiers don’t let anything sway them from their mission, not even death from high explosives. Free from her troubled past, Agent Kirsten Wren finds happiness mentoring Evan, a boy with similar talents with whom she soon forms a strong bond. Her efforts to help Dorian settle his past become complicated when a team of corporate “issue resolution consultants” continue their mission to kill a man in the afterlife. Kirsten gets involved when their post-mortem grudge match spills into the realm of the living. At the scene of a surgical explosion that gutted only one floor of a residential tower, she discovers a strange arcane circle drawn in silver. There, she senses energy darker than any wraith she has yet encountered; a force that questions everything she believes about the world. Vikram Medhi, the hacker targeted by Lyris Corporation for elimination, begs her to protect him from undead out to destroy him. With no way to track these spirits, she seeks help from an enigmatic billionaire who offers her more than a simple translation of ancient Sumerian pictographs. Chasing down a dangerous psionic criminal in the oldest lawless zone in the city, trying to protect a man on a corporate death list, and trying to keep both of them from hurting the one person in the world she loves, Kirsten must reach deep within herself to accept her destiny.

Agent Kirsten Wren has her fair share of demons to deal with—and some are literal. Despite discovering the world beyond death is more complicated than simple ghosts, she’s almost got her life in order. Her effort to adopt Evan appears to be on track, no one’s tried to kill her for a whole week, and most unbelievable of all, a billionaire is in love with her. Kirsten’s bleak childhood has left her with great contempt for the wealthy and a deep mental scar that makes intimacy terrifying. Konstantin’s high-society world is not for her, but thoughts of leaving him make her physically ill. A series of murders with ritualistic overtones leads her to suspect someone’s using paranormal means to destabilize the nation. Stuck between her tortured past, an even scarier future, and a government doubting her stories of the Abyss, she has a mere week to find the killer before all hell breaks loose. However, the demons are far closer than she expects.

Agent Kirsten Wren thought she’d seen the true face of evil, but an elder demon didn’t prepare her for an even more insidious enemy—politics. She returns to active duty after a month off to recover from what happened on the Moon, gloomy over not being able to spend all day with her adopted son. After the fiasco of her last relationship, she takes things slow with a potential new boyfriend, but wonders if she’s capable of trusting a man. Her usual routine goes off the deep end when an influential senator requests her by name to investigate a haunting at his earthbound vacation home. A string of escalating spectral assaults on random people by the same entity leaves her frustrated and unable to connect the dots. Once the angry spirit attacks her son, Kirsten suspects she’s its true target. The more she learns, the more she suspects the senator is darker than the spirit he wants destroyed. Kirsten is determined to bring him down, but doing the right thing could cost her guardianship of Evan and threaten the very existence of Division 0.
