Mare in the Meadow (Animal Ark Series #31)
Mandy and James are having trouble finding enough time to give Chamomile - a mare whose owner has left the country - all the attention and exercise she needs. When they meet Rhian, a girl who lives next to Chamomile's field, they hope she will help them out. But Rhian doesn't want to get to know the horse - and she doesn't want to tell anyone why not. Can Mandy convince her new friend to care for Chamomile - or will the horse have to be sold?
