Horse Passages — Jennifer Macaire

Voyagers from earth have not only found haven on a faraway planet, but vast herds of horses that seem to vanish as if by magic. In reality the horses are able to open passages through time and travel from planet to planet. Settlers on the Home Planet learn to tame these horses and accompany them on their journeys, following the herds through the universe. Their life, their existence, is idyllic but for the scourge of the alien Raiders, who stalk and capture the herders and their horses. Twins Carl and Meagan Cadet are the youngest herders in the Federation. Though they savor their privacy and the bond with their horses, they eventually join forces with the rowdy Jeffries brothers. Just as they are learning to live and travel together, however, tragedy strikes. No one has ever escaped the Raiders. But when Luke Jeffries and Meagan, long ago orphaned by the cruel and barbaric aliens, find themselves slaves on a mining planet, they know they must try.Yet to do so, they must first discover the key to unlock the mystery of the marvelous Horse Passages.
