Flametouched (A Chained Magic Short Story)

Young Tessa has magic - which means she must be Tested. She's not thrilled about the idea - Tessa would rather be free to choose her own way, but she's left with little choice in the matter.
The problem is, nobody returns from the Test. Nobody ever has, as far as Tessa knows. What waits behind the simple wooden door with its steel knocker? And can Tessa's wits and will survive the experience?
