Inside each rockpool, tucked into one of the infinite crevices of the tidal coastline, lies a rippling, silent, unknowable universe. Below the stillness of the surface course different currents of endless motion - the ebb and flow of the tide, the steady forward propulsion of the passage of time, and the tiny lifetimes of its creatures, all of which coalesce into the grand narrative of evolution.

In Life Between the Tides, Adam Nicolson investigates one of the most revelatory habitats on earth. Under his microscope, we see a prawn's head become a medieval helmet and a group of "winkles" transform into a Dickensian social scene, with mollusks munching on Stilton and glancing at their pocket watches. Or, rather, is a winkle more like Achilles, an ancient hero, throwing himself toward death for the sake of glory? For Nicolson, the world of the rockpools is infinite and as intricate as our own.

As Nicolson journeys between the tides, both in the pools he builds along the coast of Scotland and through the timeline of scientific discovery, he is accompanied by great thinkers. We meet Virginia Woolf and her Waves; a young T.S. Eliot peering into his own rockpool in Massachusetts. And, of course, scientists populate the pages; not only their discoveries, but also their doubts and errors, their moments of quiet observation and their realizations.
