With sales of more than 3 million books, this newest Animal Ark title will provide cozy reading for young animal lovers.

One busy Saturday morning, the delivery man brings a big surprise to Animal Ark: the tiniest horse that Mandy has ever seen! The miniature horse was actually meant for Tania Benster, a newcomer to Welford. But Tania's parents have just divorced and she's too upset to care about her gift.

Can Mandy show Tania how much this little horse has to offer?
