Publication Order of Anthologies
Emily Carter is an accomplished published author.
She is known for writing science fiction but works more in the intelligent hard science fiction vein. There she takes a look at the place that humanity occupies in a cosmos that they otherwise view as being completely vast and indifferent.
The novels that she writes put together rigorous scientific plausibility and pairs them with situations of high stakes survival. This typically results in her putting engineers, physicists, and commanders at the center of many decisions that shape history.
One of these hard science fiction books is Deep Space Expedition, the first in Carter’s The Threshold Protocol series. This is a book where a generational star ship ends up facing catastrophic propulsion failure beyond the depths of mapped space, and eventually uncovers further evidence that when it comes to its pursuit of the stars, humanity is not on its own.
Meanwhile in another book titled The Quantum Drift, a classified anomaly located close to Jupiter ends up opening up the chance of first contact as conducted through quantum transit. This means that Earth will have to take an up-close look at the risks of technological acceleration.
The fiction that Carter writes is grounded in propulsion mechanics, realistic astrophysics, and systems engineering. She does not rely on spectacle but her stories instead take a look at the mathematics of hope (while emphasizing how fragile it is), the ethics of exploration, and the consequences of discovery in the type of universe that cannot offer up any guarantees.
The work that she does is also appealing to various readers who want scientifically authentic space exploration, existential tension, and the heroism quietly carried by people who choose to go into the unknown.
Deep Space Expedition is the first book in The Threshold Protocol series by author Emily Carter. If you’ve been looking for something interesting to read and you like science fiction stories and hard science fiction in particular, this is likely a great selection for you.
The mission that they had was intended to be a simple one. They were going to cross the void, build a colony, and from there on make history. It’s been 18 months into the first interstellar voyage taken on by humanity and while on their way, a regular engine burn ends up revealing an anomaly– one that should not technically exist.
It’s a gravitational disturbance, but there’s no explanation to be found in nature. This is a structure in the void that exists between the stars. It appears to be very large and is not only metallic but an object that appears to be older than human civilization itself.
Commander Isaac Rowe is someone who has 4% fuel margin and 312 lives that have been built on his decisions. Elara Mendez is an astrophysicist that has data that may end up defying every single model that she has ever built. Meanwhile, engineer Pavel Ionescu has a drive that is being messed up by different forces far beyond his design specifications.
At the same time, Mei Okafor is the systems analyst and she has numbers that are telling her that the mission is dying. They’re saying that they are at 18% survival probability and the numbers are falling fast. It turns out that this lattice is not a trap but might end up being a road.
Using it means that you are going to have to trust alien engineering with all of the lives on board, and the line between salvation and oblivion is so thin– thinner than maybe even the space between the stars. This is the type of science fiction novel that is about a crew that finds out that humans are not alone in the universe and now has to bet it all on their interpretation of what that means for them. Check out Deep Space Expedition by Emily Carter to follow along with every word.
The Quantum Drift is the second book in The Threshold Protocol series by Emily Carter. If you thought that the first book in this series was engaging, keep the adventure going by getting your hands on a hard science fiction copy of this entertaining sequel.
It turns out that the road that was built between the stars may not have been made for us, but we are the ones who have discovered it anyway. At a multi-national deep space observatory orbiting Jupiter, theoretical physicist Dr. Alina Rao picks up on an anomaly in the spacetime curvature of the planet’s L2 Lagrange point.
It is periodic, precise, and it is far from natural. What starts as just a regular measurement ends up turning into a revelation. It is a quantum phase corridor that has been engineered and not only is it ancient but it goes on 1000s of light years forward into the galaxy.
Then a probe is sent to investigate everything– and comes back with its molecules changed. Now it is carrying atoms that have been made in another star. As a result, Rao and her team are going to have to deal with taking on the type of discovery that might just have the power to rewrite the place that humanity occupies in the cosmos.
The corridor, as it turns out, responds to observation. Every measurement that is done leads to feeding its energy. As the governments deal with control and the military factions push to get human transit, the team is dealing with a really tough choice.
They either risk destroying one of history’s greatest discoveries ever made by humans, or accept that the human race is not ready to use it. First contact came through inherited risk, not communication. Can humanity deal with what they have found out or is this simply going to show how unready the human race is for the next step of knowledge of where we stand in the galaxy?
Check out this book by Emily Carter to find out what happens and to follow along with every word from start to finish in this second installment of the series.
