"Through This House" is a short story originally published in the anthology Home Improvement: Undead Edition, released in August of 2011.
Author's Summary Edit
The knowe known as "Goldengreen" has been locked and alone since the death of Evening Winterrose...which is why it's a bit of a problem when Toby and her allies are called upon to reopen the knowe. Knowes can have minds of their own, you see, and they don't take kindly to being disturbed. And since Toby would rather keep herself and her friends alive than actually succeed in her mission, it's entirely possible that things will not end the way that they were originally intended to.
Not that failure is an option. And not that trying to be careful is going to make any difference when the problem involves not just unreal real estate, but crumbling cliff faces, giant spiders, pixies, and smart-mouthed Fetches who insist on poking their noses in where they're not wanted. Oh, and did we mention that there's no coffee?
Suggested Reading Order Edit
"Through This House" is best read between Late Eclipses and One Salt Sea, as it falls chronologically directly between these two books. It naturally contains spoilers for the first four Toby adventures.
