A lost probe returns from interstellar darkness carrying an offering humanity cannot safely refuse, or fully understand.
Fifteen years ago, the Prometheus mission vanished beyond the edge of the solar system. Its signal died. Its crew was gone. Its story was over.
Then Prometheus comes back.
Now retired scientist Dr. Nell Hadfield, the woman who designed the probe’s autonomous mind, is pulled into a global crisis when the impossible spacecraft reappears in Earth orbit, broadcasting a signal unlike anything humanity has ever seen. What begins as a scientific mystery becomes something far more dangerous: the probe is not just transmitting data. It is carrying the Method, a transformational blueprint that could remake human technology, human travel, and perhaps humanity itself.
As governments fracture, scientists race to decode the signal, and the world turns the discovery into politics, ideology, and fear, Nell must confront the one question no calculation can answer:
If the stars can be reached, what are we willing to become to reach them?
The Long Silence is a cerebral, high-stakes hard science fiction thriller about first contact, relativistic space travel, autonomous intelligence, and the cost of crossing the threshold into a larger universe.
Perfect for readers of intelligent, idea-driven sci-fi in the tradition of Adrian Tchaikovsky, Alastair Reynolds, and Daniel Suarez.

Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.

Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
