The many names of M. E. Kerr.
From Worth the Trip:
But all the while I was reading it, the voice sounded familiar to me. I attributed it to too many public-school years of being forced to watch educational films narrated by Lowell Thomas. But then I read the afterword in the book and knew immediately who Ann Aldrich was and why her voice was so familiar. It had been written by one of my favorite YA authors, M.E. Kerr.
Auuugh. So many books to search for! I'd especially like to read Shockproof Sydney Skate and Little Little.
