Jayci is just your average college student, though she's juggling some extra stuff. There's her job to help pay the rent, and the theater group she joined (Team StarKid!). She doesn't expect to have two of the boys fall for her.Chaos may or may not ensue. (Personal note from author: I may or may not suck at writing descriptions.)

Casey is a hardcore Starkid fan, who has been amazed with Spies are Forever by the Tin Can Bros. On Twitter, she sees many fans asking for a sequel. inspired by the musical and support of her best friend, she writes a script for fun, about a possible plot to a Spies Are Forever sequel, which she calls 'Spies Never Die". Casey publishes her story online, but it is then noticed by Nick Lang, who shows it to the members of TCB. After reading her script, Casey gets an email from them, inviting her to help them with a special new project. And so her journey begins. This story follows her trials as a writer for a new musical, "Spies Never Die".
