The Far Side of Promise is an anthology of short stories encompassing several genres. Into the Beneath is a short story within it that follows Kirsten Wren (from the Division Zero series) on the night she ran away from home as a child. A spirit warned young Kirsten Wren her mother would take her life. While cruel, the woman’s zealous hatred of her daughter’s psionic gift seemed unlikely to prove fatal. When one desperate ghost refuses to let the child ignore her, the eerie warning takes on a new, terrifying truth.

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.

A short story occuring two weeks after the events of Division Zero #1, and prior to Book #2 Lex De Mortuis; contained within the Divergent Fates Anthology. In Loose Ends, a false lead from an old case comes back to haunt Agent Kirsten Wren.

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.

Lieutenant Kirsten Wren has encountered Harbingers before—shadowy entities that claim ghosts with dark souls—but they don’t usually follow her home. At long last, life is somewhere approaching happy. Her adopted son has put his past behind him and she’s even finally trusted herself enough to start a romantic relationship. Best of all, no corporations or demonic creatures have tried to kill her in a whole month. Dead gang members start turning up, victims of murders with ritualistic overtones. Division 1 files them away as low priority due to their policy of letting the street trash clean itself up. However, when additional killings occur with obvious supernatural causes, Kirsten officially takes jurisdiction. In the midst of her investigation, a Harbinger attaches itself to her. The chilling ramifications of that become clear once she discovers the area’s most feared gang has developed a working relationship with the Abyss. If she doesn’t act fast, all of West City will become a hellscape.

Kirsten Wren’s job has gone back to normal—ghosts are killing people again. After twenty-three rough years, Fate seems to be giving her a break. Her adopted son is happy. The new—well, first—boyfriend is doing everything right… and she hasn’t seen a single demon in a few months. In 2419, West City is a violent place filled with poverty, overcrowding, and augmented cyber-gangs. No surprise vengeful spirits are everywhere. Compared to creatures of the Abyss, however, angry ghosts are like old friends. An unusual spike in hostile manifestations suggests something out there is stirring up spirits. Initially benign events rapidly become deadly. As the only Astral Sensitive the National Police Force has on the West Coast, Kirsten might be in over her head. The incidents continue at an overwhelming pace. Responding to so many hauntings leaves little time to find the cause of the ghosts’ agitation, but if she doesn’t do something soon… the city will descend into spectral chaos.

Techies often blame problems on ghosts in the system, but sometimes it's literal. In the year 2419, the sprawling metropolis of West City offers no shortage of ways to die. In light of all the crime, illicit chems, overpopulation, and ghastly accidents, many citizens become jaded to death. Lieutenant Kirsten Wren tries to help as many people as she can—even after they've lost their lives. Amid the chaos, a series of bizarre deaths among hackers stands out as unusual enough to draw her interest. Something technology cannot explain is happening in the GlobeNet, and it's killing people. Kirsten's investigation stirs up a far more sinister fiend than a simple angry wraith, one that won't hesitate in killing a cop to keep its secrets.
