At age seven, in 1901, January Scaller finds her first Door, painted blue in a field in Kentucky. She steps through it into another world—but only for a moment. When she returns to try to find the threshold again, it’s gone.

And so January is brought back home, to the mansion where she lives with her guardian, Cornelius Locke. Her father, Julian, is frequently absent, working for Mr. Locke collecting the curious artifacts that fill the house to draw the admiration of the men of the New England Archeological Society. January herself sometimes feels like part of the collection. But she’s not entirely left to her own devices: there’s her pulp-fiction-loving friend, Samuel; a governess sent by her father from Africa, Jane; and, of course, her dog, Bad, short for Sindbad.

At seventeen, her father vanishes. In a trunk where she believes he sends her items, she discovers and reads a book—The Ten Thousand Doors—that will unlock the secrets that surround her and, just maybe, a path to escape and her future. Complete with a book within a book, this novel is a Door readers can step through to take an unforgettable journey.
