Boo to Kurrawong! Sure, it's true that in our reality, horses don't think quite so much. But this is Middle-Earth, and a horse of legendary bloodline... it's OK for it to have a little more sentience than an ordinary horse might!
I found this story poignant, and it has a sort of sweet innocence. And I can just imagine the cruelty that might be visited on the poor animals with the misfortune to serve Mordor... urrgh.
I'm quite dismayed this work has two gushing reviews. Horses DO NOT think like people, they don't think of their own blood, they don't understand 'good' and 'evil'. They just know if someone is nice or not. You put far far too many human thoughts in the horse's head, and although the idea of behind the story is good, you have uttterly spoiled it. I guess too that I'm disgusted that one of the infamous nasty Deleterius, who shreads the works of others, is, in reality no better a writer than those she tears apart. Go, learn to write, then try this story over again!
