I'm not sure specifically as I don't know which 'handles and kia novel' you are referring to. It could be that 'handles' might refer to some sort of object handles in the story, and 'kia' could be a character, place or something unique to the novel's plot.
There are indeed such stories. For instance, in 'The Sensorites', the Doctor gets involved in a situation involving first contact and has to help smooth out the complications that arise.
I'm not sure who specifically wrote it. There are so many Harry Potter fanfic authors out there. It could be an amateur writer on a fanfic website like Archive of Our Own or FanFiction.net.

Many fanfics describe wand handles in relation to the character who wields them. If a character is brave, the wand handle might be thick and sturdy, made of a strong wood like oak. If the character is more delicate or has a more nuanced magic, the handle could be slender and made of a lighter wood such as willow, often with intricate carvings.
There could be bras of different styles, like sports bras for when she exercises, and regular bras for daily wear. Also, panties in various colors and fabrics. Maybe a silk nightgown for special evenings or a comfortable cotton pajama set.
