Heartland is a horse farm nestled in the hills of Virginia, but it's much more than that. Heartland is a place like no other - a place where the scars of the past can be healed, a place where frightened and abused horses learn to trust again. An equine flu is infecting Heartland's horses. Despite their desperate efforts, Amy and Ty cannot keep it from spreading. They try to isolate the oldest and youngest horses - the ones with weaker immune systems - but more fall ill. To make matters worse, the late summer heat is intense, Ty and Ben are at odds, and Amy feels caught in the middle. Then, just as some horses start to get better and the weather is about to break, things spin out of control. When the clouds clear away, nothing seems the same.Brooke, Lauren is the author of 'Darkest Hour' with ISBN 9780439425087 and ISBN 0439425085.
