Perfect for you if...

You love hard science fiction where the physics actually matters and the threat feels terrifyingly plausible.
You're drawn to survival stories where humanity's only hope rests on a handful of brilliant people making impossible choices.
You appreciate space opera with real stakes: when planets get destroyed, entire ecosystems die, and there's no reset button.

Maybe not for you if...

You prefer character-driven narratives where emotional arcs matter more than technical problem-solving.
You want a slower, quieter sci-fi experience rather than a high-stakes race against planetary annihilation.
You're looking for a standalone novel rather than the third book in a trilogy, even if it works independently.

About this book

Venus explodes into dust and radiation, destroying crops and half the ocean life while damaging Earth's ozone layer. Days later, moon rock from an Apollo mission lands on a Scottish lava crag and triggers a catastrophic chain reaction. The ground begins melting into expanding pools of dust. The cause is Moonseed, a nano-virus that is part machine and part life-form, capable of destroying planets. It arrived decades ago and has already demolished Venus. Four scientists must race to stop the virus and prevent Earth's extinction. Their mission takes them from Earth's inner core to the Moon in an attempt to cut off the threat and save what remains of the planet.
