out of curiosity I started looking up books written by twelve year olds and
BIRDS THAT FIGHT WITH SWORDS
zero and i found this in a thrift shop and. it’s a ride. it’s very competently written, on a technical level- you wouldn’t think it was a twelve-year old until you started paying attention to what the words were saying
the evil birds are so evil, like- this is a twelve-year-old with a very twelve-year-old understanding of how good and evil work. evil is like, a primordial force of badness, sufficient by itself to motivate the villains to atrocity- and naturally, it is opposed by a supernatural deity of pure Good, the titular Swordbird. the birds fight with swords either because one side is Evil, or being tricked by Evil. it’s very zoroastrian, actually. no, wait. zoroavian. it’s amazing.
theres an official and somewhat longer prequel wherein all birds are tyrannized by a corrupt archaeopteryx empire and a young Swordbird (who is not the Swordbird yet) has to go on a quest to… get swords
