Massif

The epic scifi debut by the beloved multimillion copy bestseller unmissable for readers of Andy Weir and the perfect gateway into science fiction for fantasy fans

By: Garth Nix

RIDE A MASSIF TO A NEW STAR SYSTEM.
FIGHT THE ENEMY YOU FIND THERE. REPEAT.

It's business as usual for Ship Leader Parnell Shi-Sawahla and the crew of the corvette Sassafras. Ride a Massif to a new system, fight the enemy, repeat. For more than two hundred years humans have been hitching rides on these sentient, starfaring mountain ranges, colonising planets and exporting an on and off again war between Earth and Mars.

But the big questions are always there, behind every battle, every new colony, every new star system discovery.

Why do the Massifs carry humans to the stars?

Why do they help us export our wars?

What's in it for the Massifs?

Ship crews aren't supposed to ask these questions, they aren't supposed to think about these questions, and they definitely aren't supposed to go deep and talk to Massif avatars. But now Parnell and his tight-knit crew must try to find the answers, to save not only themselves but the future of humanity.

From the multimillion-copy bestseller behind many beloved fantasy series including The Old Kingdom and The Left-Handed Booksellers of London, comes his first ever adult sci-fi novel with an epic and poignant story of sentient starships, galactic warfare, and the bonds a crew forms in the cold black of space. Massif is utterly unmissable for readers of Andy Weir and Pierce Brown - and it's also the perfect gateway into science fiction for fantasy fans.
