Bromeliad Trilogy Series by Terry Pratchett, Mark Beech

Under the floorboards of the Store is a world of four-inch-tall nomes that humans never see. It is commonly known among these nomes that Arnold Bros. created the Store for them to live in, and he declared: "Everything Under One Roof." Therefore there can be no such thing as Outside. It just makes sense. That is, until the day a group of nomes arrives on a truck, claiming to be from Outside, talking about Day and Night and Snow and other crazy legends... moreUnder the floorboards of the Store is a world of four-inch-tall nomes that humans never see.

And they soon uncover devastating news: The Store is about to be demolished. It's up to Masklin, one of the Outside nomes, to devise a daring escape plan that will forever change the nomes' vision of the world. . . . less

In an abandoned quarry, pampered Store nomes have trouble with farming, no heating, and too much open space. Suddenly with a posted paper, the quarry will be reopened.Masklin ventures with Gruder, while Grimma and Dorcas try to cope at home. Sort of cliffhanger end is line "I'd very much like to know what Masklin has been doing these past few weeks."

Somewhere out there, the ship is waiting to take them home . . . Here's what Masklin has to do: Find Grandson Richard Arnold (a human!). Get from England to Florida (possibly steal jet plane for this purpose, as that can't be harder than stealing the truck). Find a way to the launch of a communications satellite (whatever those are). Then get the Thing into the sky so that it can call the Ship to take the nomes back to where they came from.It's an impossible plan... moreSomewhere out there, the ship is waiting to take them home . . .

They have made their homes beneath the floorboards for generations and no longer remember -- or even believe in -- life beyond the Store walls.Until the day a small band of nomes arrives at the Store from the Outside... moreIn a world whose seasons are defined by Christmas sales and Spring Fashions, hundreds of tiny nomes live in the corners and crannies of a human-run department store.
