one of the first marguerite henry books i read, i was surprisingly disappointed. i felt the story didn't move fast enough, and the details she included weren't interesting enough, that i never read it again. (i reread everything when i was younger - honestly. if i didn't read it at least twice, something was really wrong.) however, i want to pick it up again and see what i think now, because it does tell the true story of how the thoroughbred was "created" out of three strands of arabians in the bedoin desert.
and the history of horse-racing is actually totally interesting, and completely fascinating. bloodlines are incredibly thorough - i think every registered thoroughbred in the the jockey club has to be able to trace its lineage back to the godolphin arabian - or at least, to another horse that can connect back. it's kind of like playing "who begat who?" in the bible, except with horses. and people that follow the bloodlines are fanatics about it. it's really kind of incredible.
