Only As Safe by Mark A. Garland and Lawrence Schimel
My rating: 3 out of 5 stars
On his sixteenth birthday, Lord Turell saw the blond-haired raiders returning to Brackham almost a year since they had killed his father during their last raid. Learning from the previous year, Turell and his captain have a plan only to find out the raider’s have changed tactics with a ram instead of digging under the wall. The defenders hold as best they can as Turell remembers how he was saved the previous year in the well by the aid of a naiad (who might be his mother). Unfortunately the raiders are on the verge of victory including Turell getting captured but the water from the well is killing the invaders including the foreign king thus saving the day.
I described this story not as well as it deserves, it was a nice story.
