As if the devil’s food cake at her wake and the white fat pants she’s stuck wearing for eternity weren’t bad enough, tween angel Gabby is quick to discover that being a Bright can be fun. The city of Cirrus, Skyphones, and InnerNets are all the rage. And working through the training levels to get her wings doesn't seem too hard.

At the ceremony, Gabby is horrified to find out that she has to protect her school nemesis and ex-beffie, Angela, who is now dating Gabby’s mega-crush. But instead of protecting Angela, Gabby plays a few pranks (since when is sticking toilet paper to her shoe or putting spinach in her teeth a sin?). They seem harmless until the school dance sabotage gets out of control, forcing her SKYAgent, Clarence (with anger management issues of his own) to put her on probation, threatening her eternal future.

Determined to right her wrongs and fix the mess she caused, Gabby steals an ancient artifact that allows her to return to Earth for just one day. This violation unknowingly kicks off a series of events and unleashes a dark side. Gabby soon learns what can happen when you hate someone to death.
