Vice President JD Vance, a convert to Catholicism whose faith has been central to his adult life, writes about his religious journey in a new book that could ultimately serve as a sort of origin story for a future presidential campaign.

"Communion: Finding My Way Back to Faith" comes out Tuesday from Harper, and The Associated Press obtained a copy ahead of its release.

The HarperCollins imprint also put out "Hillbilly Elegy," the best-selling memoir from 2016 that helped make Vance a national figure.
