"One cold winter night, Sweet Pea the orphan lamb becomes very ill. Everyone in the farmyard is concerned for her. Under the watchful care of Farmer John, Laddie the sheepdog, and Dr. Alison the mobile veterinarian, she slowly recovers. Dr. Alison tells Swet Pea she can have a sleep over with her friends to celebrate as soon as she is well again. The day finally comes when Sweet Pea is feeling better, so her closest friends Sunny, Prem, and Violet join her in the greenhouse for an imaginative "SheepOver" celebration."--Back cover
