Sarah Bowman and Liz McCree (two fourteen year old girls) are best friends and one of the many things they share in common is their love for horses. They've been riding since they were little but they live in the city and riding at a stable is not the same as riding out in the country where all the wild and adventure they dream of is.
School has just finished for summer break and Liz and Sarah are going to Liz's uncle and aunt's ranch for the summer. The ranch is surrounded by wilderness and adventure is bound to find them.
