It was a great invention and I was proud of it. The idea had come to me this afternoon, during a slow spell. I’d been stressing over the enormous Shade outside the bookstore, when suddenly a light had gone off in my head, or rather, several dozen.

I’d flipped the sign and locked up at seven on the dot, raced down the street to the sporting goods store on the corner, and bought everything I needed, from the biking helmet, to batteries, to brackets and caving lights, to tubes of superglue, to Velcro bands as an added precaution.

Then I’d come back to the bookstore, dialed my iPod to the latest playlist I was crazy about, cranked it up to a smidge below deafening, and gone to work.

I shook my invention. I dropped it. I kicked it, and still all parts remained intact. Superglue: after duct tape, a girl’s best friend.

I was satisfied. With three quarters of an hour until my Voice lessons, I had time to test the device, and still make it upstairs to freshen up a bit, not that I cared how I looked around Barrons. It’s just that in the Deep South, women learn at a young age that when the world is falling apart around you, it’s time to take down the drapes and make a new dress.

Every truly inspired invention needed a catchy name, and I had just the right one for mine. Who needed the Cuff of Cruce to walk among the Shades?

I slipped the biking helmet on my head and strapped it securely beneath my chin. It fit snugly so it couldn’t fall off in the heat of battle. I could do a flip (if I could do a flip) and the thing would stay stuck to my head. I’d superglued dozens of Click-It lights all over the surface of the helmet. Brackets stuck out several inches from both sides and the rear, with spelunker lights attached, pointing downward.

I swept my arms out and took a deep bow: Presenting the MacHalo!

With all the lights turned on, the helmet created a perfect halo of light around my entire body, down to my feet. I loved it. If it hadn’t been so bulky, I might have tried sleeping in it. As an added precaution, I strapped on the Velcro wrist and ankle bands I’d cut little pouches in, and sewn Click-It lights into. All I had to do was hit my wrists and ankles together and the lights clicked on.

I was ready.

But first, I wanted a test run inside the store before I went outside.
