Autumn. Season of mists and mellow fruitfulness. That's what it felt like for Keats in 1819.

How about Autumn 2016?

Daniel is a century old. Elisabeth, born in 1984, has her eye on the future. The United Kingdom is in pieces, divided by a historic once-in-a-generation summer.

Love is won, love is lost. Hope is hand in hand with hopelessness. The seasons roll round, as ever.

Ali Smith's new novel is a meditation on a world growing ever more bordered and exclusive, on what richness and worth are, on what harvest means. This first in a seasonal quartet casts an eye over our own time. Who are we? What are we made of? Shakespearian jeu d'esprit, Keatsian melancholy, the sheer bright energy of 1960s Pop art: the centuries cast their eyes over our own history-making.

Here's where we're living. Here's time at its most contemporaneous and its most cyclic.

From the imagination of the peerless Ali Smith comes a shape-shifting series, wide-ranging in timescale and light-footed through histories, and a story about ageing and time and love and stories themselves.

Here comes Autumn.
