Our view
“An Acceptable Time” brings Madeleine L’Engle’s “Time Quintet” to a reflective close, centred on Polly O’Keefe. Her story echoes the earlier adventures of Meg Murry and Calvin O’Keefe, her parents, and L’Engle threads philosophy and faith through it; even the title comes from a psalm. Some readers find this fifth volume weaker than the earlier ones and loosely plotted.

About the book
An Acceptable Time is a 1989 young adult science fiction novel by American author Madeleine L'Engle, the last of her books to feature Polyhymnia O'Keefe, better known as Poly or Polly. Marketed as part of the author's Time Quintet, An Acceptable Time connects Polly's adventures with those of her parents, Meg Murry and Calvin O'Keefe, which take place a generation earlier. The book's title is taken from Psalm 69:13, "But as for me, my prayer is to You, O Lord, at an acceptable time."
