"Hilda is a pig who lives in a small tin house at the foot of a hill. Life is peaceful, if a bit uneventful, and she is always where she expects herself to be. At the top of the hill lives a baby who is never where people expect him to be, which is why he is known as the Runaway Baby. When a chance escape in his carriage brings the Runaway Baby zooming full-speed toward Hilda, their worlds collide, and the beginnings of an unlikely friendship promise to make Hilda's life a little less quiet and a lot more interesting"--Dust jacket flap.
