ARCA: Threshold
ARCA: Threshold is the first book in the ARCA saga.
We were born orphans into an indifferent universe. What will become of our legacy the day it becomes aware of our existence? — Anonymous Record
In the near future, humanity lives sustained by a global interconnected network, where every aspect of life is protected by infallible systems. But something has breached those defenses. An anomaly. Strange, inexplicable, impossible.
From one of the network’s cores, a system operator comes into contact with the anomaly. What seemed like a simple technical glitch shakes her neural implant, leaving an indelible mark and forging a connection to something beyond our world.
Humanity stands on the brink of irreversible change. An unknown intervention has breached the foundations of our connected world, moving through its systems with unsettling impunity.
But this intrusion is not merely a threat; it is an inflection point—an instant where the established order fractures, and the unknown shifts from a possibility to an inevitable destiny.
On the other side of this threshold, will we still be the same?

About the author
Esteban E. Delgado
2 booksEsteban E. Delgado was born in Argentina, but his Swiss roots compelled him to navigate between both cultures—feeling a part of the two, yet never fully belonging to either. He studied architecture in Buenos Aires and currently lives in Switzerland with his wife.
Esteban’s fascination with science fiction lies in its ability to inspire reflection beyond the limits of our nature. He has a strong preference for stories that place humanity and its dilemmas at the center, such as Contact by Carl Sagan or Childhood’s End by Arthur C. Clarke.
ARCA: Threshold is his debut novel and the first installment of a trilogy that explores the impact of an intervention from another world, marking a turning point in human evolution.

Sorry but this story was all over the place and I had a hard time keeping track of who was doing what to whom for what reason. I liked the concept of the storyline I just wasn't crazy about how it unfolded.
Plus it leaves you on a cliffhanger and any author that can't finish a story in one book I don't need to bother with. So I won't finish the series or look for anything further from this author.

There was a lot of story building which I enjoyed. the two sides of the story have yet to meet. I was hoping to see how they intertwined. I don’t love books left off in cliff hangers like this but I would be interested to read the next one to continue the story.
