An urban, multi-cultural family spends a hot summer night glued to the tv set, computer... until the power goes out. The book is in somewhat of a comic book format, with large panels and a few speech balloons. There's a generous use of cross-hatching, and what looks like digitally-added color. I loved the hidden little details, such as Thomas Edison's portrait looking disapprovingly on as the protagonist initially settles in for a night of video games.
Once the lights are out, the book switches to a subdued palette of mostly blue. Forced to hang out together, the family tries playing with a flashlight making shadow puppets on the wall, until they decide to go up to the roof and watch the stars. Then they head down to the street where's there's a block party atmosphere. An ice cream vendor is giving away ice cream (before it melts, I assume) and kids play by a splashing fire hydrant.
When power is finally restored, "everything went back to normal... but not everyone likes normal," and here we see the family purposely turning off the lights, and playing a board game together. This book would make a great bedtime story, and hopefully will inspire people to try out a night off-the-grid.
