A notebook waits in a Maine cottage for more than a century.

When Marisol Brock-Whitebear receives a call from an estate-clearance specialist at the old Halberstam-Vandermeer cottage, she expects a careful appraisal. What she finds instead is a leather-bound notebook: 118 pages, forty-seven handwritten poem drafts, dates from 1908 to 1916, and an inscription that may connect the volume directly to Robert Frost.

But a discovery this significant cannot rest on excitement. It must survive evidence.

From Marginalia Books in Halsey Harbor to historical societies, special collections, correspondence archives, and Frost-related institutional records, Marisol begins the slow work of authentication. Every date must align. Every letter must be checked. Every provenance claim must hold.

Then a counter-claim threatens the notebook's history, forcing Marisol to prove not only what the object is, but where it has been and who had the right to keep it.

The Frost Notebook is a literary archival mystery about rare books, historical evidence, professional care, and the quiet suspense of proving the truth page by page.
