📦 Shipping Notice for Print Books
To keep shipping costs as low as possible, we recommend placing smaller print book orders whenever practical.

If you're purchasing several print books, placing two or more smaller orders will often reduce your shipping costs.
The Cornerstone Story Collection — High School
Two complete novellas in one volume, written for readers in grades 9–12 — substantial, unhurried historical fiction about crossing the distance to someone the world says is beyond reach.
The Enemy's Door. Sigrid has never seen the farm across the valley as anything but the house of her family's enemies. Then, through one long and terrible night, a child lies dying under that roof - a child she is forbidden to save - and an old hatred is weighed against a single life.
The Runaway. When his nerve breaks and disaster follows, Ewan runs north into the winter rather than face his shame at home. Callum goes after him alone - not to drag him back, but to walk him home of his own will, because a fetched man only runs again.
Set in richly imagined working worlds — herring boats and hill farms, smithies and droving roads — these are stories that trust their readers: no easy lessons, no thin characters, only real people carrying real weight and choosing well at real cost. Together the pair turns on mercy, reconciliation, and steadfast loyalty.
Ideal for the classical or Charlotte Mason high-school reader, for family read-aloud and discussion, and for anyone who wants literature that forms character without ever preaching. A companion to the elementary volumes of The Cornerstone Story Collection, written for older hearts and longer attention.
This volume includes two complete novellas:
- The Enemy's Door
- The Runaway
Choose your format: Paperback (6 x 9 in, printed and shipped) or EPUB ebook (instant digital download).
