Six hundred photographs. One forgotten child. And a secret someone is willing to kill to keep buried.

When Augusta "Gussie" Pratt dies, professional genealogist Maggie Penhallow is entrusted with a remarkable inheritance: a red leather album containing six hundred photographs collected across generations of Millbrook history.

Most are unlabeled.

But every photograph carries a code.

And one image changes everything?a young woman in 1907 holding a baby whose identity could finally answer the question Maggie has been chasing since she first came to Millbrook.

Before she can finish decoding the album, Gussie's grand-niece is found murdered inside the Pratt house. A second photograph album has disappeared. Someone has been searching the family records?and whatever they found was dangerous enough to kill for.

With Detective Ben Holloway investigating the murder, Maggie follows a trail through century-old photographs, parish registers, forgotten letters, inheritance records, and family connections that were never meant to surface.

But this case is different.

Because at the end of the trail lies not only the truth behind a murder, but the final missing piece of Maggie's own family.

Some families preserve their history in photographs. Others hide it there.

Bones, Books, and Bloodlines is the sixth and final book in The Millbrook Genealogy Mystery Series, a mystery series for readers who love genealogy, buried family secrets, historical records, small-town investigations, and intelligent female sleuths.

The records have been waiting.

Maggie is finally ready to read them.
