In a world that isn't short of darkness, there could be few more urgent priorities than to spend time rehearsing for ourselves why life - despite all its challenges - still has so much to offer us; why there are still so many reasons to be hopeful.

The book is an eclectic collection of anecdotes and arguments, vibrantly illustrated with artworks and photography, that remind us why we should remain hopeful when all else fails. Across a series of short essays, we learn why we still have the right to feel purposeful and buoyant despite everything that is challenging: because there is still so much more to discover, because we can delight in summer days and the light of dawn, and because we don't require perfection for things to feel good enough.

In a tone that avoids the pitfalls of sentimentality and cynicism, the book urges us to reconnect with our more resilient selves, bidding us to recover faith in what is still possible. At points funny and always encouraging and kind, here is an ideal friend to guide us back to courage and delight.
