A Shepherd's Christmas Story

Why did God make this amazing announcement to a family of shepherds?
This story offers one possible answer to that question. Ten year old twins Samuel and Hannah live their lives helping their five older brothers tend the family's sheep in the hills around the small village of Bethlehem. One night an angel appears to Samuel in a dream with a cryptic message that the twins struggle to understand.
After a long day, the twins are awakened in the field to see the heavenly pronouncement of the birth of the Messiah in their own town of Bethlehem. How does Samuel's dream help his brothers solve the problem of locating the manger where the Angel said the baby was born? And what special blessing awaits them there?
