Mark Button and his wife eagerly await the birth of their first child — or rather, children, as Ronnie is pregnant with triplets. However, Mark's hopes and dreams are dashed in one horrible moment, when — on Mother's Day — Ronnie tragically dies without warning. Then Mark meets Diane, and in time they build a new life together — never forgetting how precious and delicate life can be. Desiring to always "be there" for their first child, they write her letters — the first within hours of her birth. The envelope simply states, "To be opened on the day your first child is born." Mark and Diane have continued this tradition, and now each of their three children has a Letter Box filled with special memories and encouragement for the future. Complete instructions for creating personalized Letter Boxes are included.
