Acting jealous was wrong, and Kat felt happy with her life...even if she wished she could brag about how she saved lives and defeated an evil genius today. Sometimes, having a secret identity stunk.

Sam [the family dog] had no idea that his fellow pet had joined a crime-fighting spy agency, and Kat wanted him to stay that way. Her identity was top-secret.

Never in a million years did she expect to be doing her first real mission with Agent Ace Knight, the number one spy in history!
