I just finished the last book in Elizabeth Enright’s Melendy Quartet, and I truly wish there were more; I find her writing so very enjoyable (and impressively not dated for someone who was writing in the 40s and 50s). Spiderweb for Two: A Melendy Maze was a lovely way to end the series, though…we can see glimpses of the Melendy children nearing adulthood, and the ending provides closure in an unexpected way. This one features primarily Randy and Oliver, since their older siblings are away at school, and they make an endearing team as they follow clues to a mysterious treasure hunt into all sorts of unexpected places.
Unfortunately, even the amazing Salt Lake County library system only has certain titles by Enright–the Melendy Quartet, her two Newberys, and the sequel to one of them. I put in an inter-library loan request for another title of hers that looks good, so we’ll see how that goes. In the meantime, all of the ones in the library system are well worth your time!
