Freckles, by Gene Stratton Porter. Freckles was long my ideal of manliness.
The Voyage of the Dawn Treader, by C. S. Lewis. When reading this I experienced what Lewis in Surprised by Joy called 'northernness.' This book made me long for heaven.
Eight Cousins, by Louisa May Alcott. I delighted in the relationship the one little girl had with her seven boy cousins. It made me want brothers.
George MacDonald's fiction which was edited by Michael Phillips.
Brock and Brodie Thoene's books, especially the ones set during WWII.
The Hiding Place, by Corrie Ten Boom.
The Anne of Green Gables series, by L. M. Montgomery.
My Lady of Doubt, by I'm not sure who. This was a romance set during the American Revolution.
Much Ado About Nothing, by William Shakespeare. Is a 15yo still a child? There was a time in my life when I could recite most of this play, thanks to repeated readings and watchings.
Mostly, though, I read junk as a child.
