Heirs to a family legacy with a first child on the way, Mark and Katie MacDonald are caught up in mysterious events connected deep in Mark's family history and our nation's past.

The remarkable discovery of Mark's great-great grandfather Sam's Civil War journals beckons Mark and Katie to trace the MacDonald line back to one of the darkest hours of American history. Here they realize both their roots and their calling. And like Sam, they are propelled into spiritual warfare and bloody battle for the nation's soul.

Why are their unseen adversaries so bent on Mark and Katie's destruction as they contend with powers who delight in drawing bloodlines through history--connecting our nation's bloody past to crises of the modern day?

"Reading Bloodlines was like dining on a thick piece of steak. So many Christian novels today are little more than a slice of baloney." Louisa Murray, Reader

But Mark and Katie are also heirs of another bloodline that flows from their master who sits on the throne of heaven. Unseen allies come to their aid and help them battle and see life prevail over death.

Whence comes evil? As Sam faced the darkness over a hundred years before, Mark and Katie must find the faith and strength to prevail, both for themselves and generations to follow.
