100 Cupboards book 1 by N. D. Wilson

Used. Paperback. When Henry York wakes up to plaster raining down on his pillow, the last thing he expects to find behind his bedroom wall is a whole lot of baggage—literally. N. D. Wilson’s delightfully inventive portal fantasy swings open a century of mysterious miniature doors, each one leading to a wildly different world begging to be explored. It is a wonderfully whimsical riff on traditional world-hopping tropes that treats Kansas like the jumping-off point for grand, perilous geography.
