Before the attacks, Rose’s life was simple. Before there was mass violence in America, she was a university student in Liverpool. Before her roommate was savagely attacked, she wanted to make the world a better place. That was before the zombie outbreak. Now, Rose and her best friend Lyra are forced to flee their flat and find refuge onboard a yacht with a group of armed survivors. Although safety seems likely on the open sea, it’s only a matter of time before a new outbreak occurs.

At sunrise, the dead began to walk the earth. Our days were numbered. The world was over. One month after the virus took over the United States of America and turned its inhabitants into ravenous, flesh-eating monsters, Dakota Travis and his friend Steve Earnest have been barely surviving. Hiding out in an abandoned apartment building, they struggle to live in a world where danger lies around every corner and is not limited to only the threat of the walking dead. Their latest supply run almost ended with their deaths. When a local gang violently uproots them from their shelter, there is little they can do but run. Their flight finds them sanctuary one town over in a converted insane-asylum with members of the United States military. While things should be safer, an underlying tension begins to rule their lives as Sergeant Armstrong, leader of the small unit, begins to succumb to insanity. Tension runs high within the asylum. When all that separates them from the undead is a chain-link fence, Dakota begins to wonder whether or not they might be safer outside, especially when his feelings for another man leave him an open target to the disaproving within their midst.

Months after the zombie outbreak that decimated the world’s population, Rose, Dakota, Erik and Ian embark on a routine supply run only for it to end in disaster. Ian is killed instantly. Erik, meanwhile, is scratched. Unaware if such a wound will leave their companion helpless to the zombie virus, the party waits to see if Erik will succumb to infection. When he doesn’t, it seems too good to be true. But Erik isn’t out of the woods yet. With fever symptoms leaving him bedridden, it’s obvious that he’s going downhill—and fast. And only a chance communications with an infectious disease specialist in the capital offers their only chance of hope.

In this conclusion to Kody Boye’s DAYLIGHT CYCLE, winter is falling, and bringing with it even more dangers. With the undead hordes still present, and the need for supplies growing each passing day, Dakota Travis and Rose Daniels decide to enlist within the Runner’s Corps: the infamous supply running gang that scours the city for anything of use. Fortunately for them, they are skilled survivors, and have the chance of living outside the fort’s protective walls. Unfortunately, their predicament is only growing worse. As their first supply run ends, and a chance encounter with an infamous plant walker brings Rose and Dakota into the limelight, the powers that be decide to orchestrate a task for the survivors—one that may save humanity, or potentially destroy them all.
