This Summer the girls became a gang. They call themselves the C.H.I.X. after the first letters of their names and the chickens they look after.

After looking after Charlie's grandma's chickens, best friends Charlie, Hannah, Izzie and Xa (Alexandra) form a secret club formed by the first letters of their names. They are the C.H.I.X. They wear a feather around their necks, look for adventure and swear an oath to never eat poultry!

Together they promise to keep each other's secret, and have the best adventures ever! Even when a bunch of boys puts their friendship to the test.
