Mr. Mendlebee's Pandimensional Literary Repository (and Yarn) by Rebecca McKee

The Midnight Library meets The Ten Thousand Doors of January in this mesmerizing debut about a magical bookstore’s staff who must risk everything to stop the unraveling of the universe.

Stick your nose in these books and they just might bite.

Living at the center of the universe, Mr. Mendlebee’s Pandimensional Literary Repository (and Yarn) is home to lost things, forgotten objects, and dark and dangerous items best left unseen. With help from the Yeti-like Book Keeper, wizened Yarn Weaver, fish-out-of-water clerk, and Muriel the cat, the seaside store keeps the universe spinning as it should while opening its doors only to those who need it most, with one caveat: once you’ve visited, you may never return.

But when Violet, repository resident and personal friend to Mr. Mendlebee, starts seeing ghosts, the store allows its first repeat customer: Rachel, a young woman who may be the key to unlocking the secrets hiding within Mr. Mendlebee’s. Haunted by an echoing knock that sounds from nowhere, the bookstore’s staff enlists Rachel’s help to discover what’s rotten at the heart of the repository. As they do, these misfits and magical mavericks form a bond as solid as steel and as true as their hearts. But will their little community be enough to save the bookstore… and the world?

Because Mr. Mendlebee’s is coming undone, and won’t stop until the truth is out.
