Leigh grew up in Rotterdam, drawn to the waterfront as an escape from her unhappy home life and volatile father. Enchanted by the undersea world of her childhood, she excels in marine biology, travelling the globe to study ancient organisms. When a trench is discovered in the Atlantic ocean, Leigh joins the exploration team, hoping to find evidence of the earth's first life forms - what she instead finds calls into question everything we know about our own beginnings.
Her discovery leads Leigh to the Mojave desert and an ambitious new space agency. Drawn deeper into the agency's work, she learns that the Atlantic trench is only one of several related phenomena from across the world, each piece linking up to suggest a pattern beyond human understanding. Leigh knows that to continue working with the agency will mean leaving behind her declining mother and her younger sister, and faces an impossible choice: to remain with her family, or to embark on a journey across the breadth of the cosmos.
Astonishing... Beautifully written, richly atmospheric, full of brilliantly evoked detail, never sacrificing the grounded verisimilitude of lived experience to its vast mysteries, but also capturing a numinous, vatic strangeness that hints at genuine profundities about life. Nobody else writes like MacInnes, and this magnificent book is his best yet -- Adam Roberts ― Guardian
Monumental... In Ascension rarely slips from G-inducing pace. It's that rare thing: a big, brawny novel of ideas that's actually readable. And for that considerable achievement, MacInnes deserves praise. It's no small thing, after all, to reach for the stars -- Alex Diggins ― Telegraph
To the handful of recent classics such as Richard Powers' The Overstory and Kim Stanley Robinson's The Ministry for the Future can be added Martin MacInnes' In Ascension... The richness of the novel is endlessly rewarding. In Ascension is a far-reaching epic that blends a deep scientific knowledge with a wide-eyed wonder at our place in the universe -- Carl Wilkinson ― Financial Times
Martin McInnes's imagination knows no bounds: he unites the unplumbed depths of the oceans to the infinity of interstellar space in his bravura, breathtaking, audacious In Ascension. No novel I know has conveyed, in such a shiveringly exciting and original way, that old truth: We are all made of stardust. Like Ted Chiang's 'Story of Your Life', and Jeff VanderMeer's 'Southern Reach Trilogy', this is an instant classic. Read it and feel awe and wonder. ― Neel Mukherjee, author of A State of Freedom
