The Magic Christmas — Francine Pascal

When Jessica and Elizabeth Wakefield's grandparents give them a pair of matching antique dolls for Christmas, they're a little surprised. Their grandparents should know they're too old to play with dolls! Then the twins learn that the dolls are a family legacy from a past generation of twins. But that's not all that's special about the dolls. Before they know it, Jessica and Elizabeth are thrown into the most magical adventure of their lives. And along the way they learn what being twins--and best friends--really means.
