Imagine a world in which you could take back the stupid thing you just said, unspill the coffee, avoid the accident, roll life back thirty seconds and do it over again - this time the right way. In Etgar Keret's universe, all things are possible. A man can take a yoga class that genuinely transforms his life.

A son has the chance to redo a fateful exchange with his father. An alien can offer a guided tour of the destroyed earth. And an angry squirrel can wreck a wedding.

Ranging from sci-fi scenarios to fictional thought-experiments and short vignettes, the stories here all deliver the irreverence, surprises, existential unease, hope and humanity we have come to expect from Etgar Keret - one of the most original and entertaining storytellers at work today.
