I loved Madeleine L'Engle's work. Strangely, the novels of hers I loved best were not the fantasy series, beginning with A Wrinkle in Time, though that was the first of her books I read and of course the most famous. I thought her best books were the ones in a series of vaguely mystery suspense stories, starting with The Young Unicorns, and continuing through The Arm of the Starfish and Dragons in the Waters. Who can forget Canon Tallis, a marvellous character?
And A Ring of Endless Light is probably her best book of all. It's a lovely novel, less well known than it should be.
Her work was always thoughtful and filled with light. Her death is a sadness, but we have a great legacy in her books.
