The subject is simple and can be easily banana skin: one day in a huge shopping center. We follow several people that day who question the meaning of their existence in relation to this sprawling universe. We find the employee who wishes to resign security to finally find its identity, the new client who faces somehow the habits and customs of the store, the former client relegated to stowaway, literature department manager who takes to Joan of Arc and especially unpayable 7 brothers in command of this ship. The theme is not new, yet it is treated here both ruthless and lightness. Some scenes are hilarious, while others make us question our consumer society, without ever falling into a boring moralizing through. In a very different style and less rich literary sense, there is a little something that reminds Zola and Au Bonheur des Dames.
In short, this novel is a worthy and even very worthy representative of the SF without spaceship nor ruthless monster.
