Sanaka Hiiragi's The Lantern of Lost Memories is a healing, uplifting Japanese novel about family, love, loss and humanity, and what life is really about.

One photograph, one treasured memory, one chance to go back . . .

Imagine waking up in a cosy photo studio in the mountains, between this world and the next. A kind man hands you a hot drink and a stack of photographs, one from every day of your life. There are hundreds, even thousands of them. They capture your best days and your worst, memories you treasure and those you try to forget. And then there are the rest, those in-between days that we didn't know were leading to the great highs and lows. Then, you are asked to pick one photograph from each year to be placed in a beautiful Japanese lantern, to be set spinning so that your life will flash before your eyes before you move on.

This is the task set for each guest who arrives in Hirasaka's photo studio. Like our most thumbed-over photos, our favourite memories can be tarnished in time too, so Hirasaka guides the guests back in time to relive one special day over again, to take a fresh photo and find peace.

If you could relive one day of your life, which would it be?
