This book is set in a future in which people only live one day in seven. Six days in every week you would be in suspended animation. People share their houses and apartment with the people of the other days. The biggest crime is daybreaking - living on more than one day, and of course our lead character is such a daybreaker.

I thought that the basic idea of this book was extremely well handled. Just enough was mentioned of the science involved to make it understood. The main character(or characters as he has more than one personae) is (are) well written and engaging. And the story certainly does not disappoint. The only slight down I felt was the story was concluded in a fairly abrupt manner, but that is not too great a detriment.
