The arrival of baby twins, less than two years after that of their older sibling, sends Michael McGirr in search of an ancient practice for which bed is the ideal setting. It's called sleep. In this book, both a personal journey and a profound exploration of one of life's true constants, Michael muses on the many benefits of sleep, mourns its demise, and explains aspects of its strange personality. And despite their reluctance to ever all be asleep at the same time, he celebrates the three small children who came to him after a long vocation as a Catholic priest and brought him such joy and tiredness.
