The Gavin Code

The Gavin Code is about a girl named Nagiola (Normally called Nagi) who is accused of vandalism she didn't do, and has a mom who disowns her.  A hard life for a twelve year old!  But she knows how to get over hard times.  You see, she collects plastic spoons.  On these spoons, she makes a ton of lines and throws them out the window to her next door neighbor, Ivoranana (Normally called Ivora).  Ivora deciphers them and sends back another code.  They call this, 'the Gavin Code'.  They came up with this name from the people who know the code.  Nagiola, Ivoranana, Vacey, Annara and Gavin.  The initials of these kids spell Gavin.  It goes from least important to most important.  Gavin is actually third most important, but 'Avgin' didn't sound as cool as 'Gavin'.  Annara is not super fluent in the code, so she comes second.  Vacey excels at the code, but she hardly uses it.  Ivoranana is not the best at speaking it, but she uses it all the time.  And Nagiola invented the 'Gavin Code', so she is most important.
This is how Nagi's life goes, writing codes and sharing them with her four club friends.  But as vandalism keeps being done on the school, in a code very similar to the Gavin Code, these five friends must investigate, and their only way to keep secret is the Gavin Code.
