Today would have been Madeleine L'Engle's 100th birthday. For #lengle100, here's my shelf of treasured, obviously much-read paperbacks, dominated by you-know-who. The characters I met in these pages were bright, flawed, conflicted, confused, brave, foolish, and above all, human. (Even the seraphim.) Grateful to L'Engle for showing the world in all its dark and light, and the responsibility each of us bears to push the balance toward the latter.
