Centaur Rising — Jane Yolen

One night during the Perseid meteor shower, Arianne thinks she sees a shooting star land in the fields surrounding her family's horse farm. About a year later, one of their horses gives birth to a baby centaur. The family has enough attention already as Arianne's six-year-old brother was born with birth defects caused by an experimental drug―the last thing they need is more scrutiny. But their clients soon start growing suspicious. Just how long is it possible to keep a secret? And what will happen if the world finds out?

At a time when so many novels are set in other worlds, Jane Yolen imagines what it would be like if a creature from another world came to ours in this thoughtfully written, imaginative novel, Centaur Rising.
