Noah's Compass by Anne Tyler

When sixty-one year old Liam Pennywell is let go from his job teaching fifth grade at a private boys school in Baltimore, he decides to downsize to a smaller apartment. After moving in, he wakes up in the hospital with no memory of being knocked unconscious by an intruder the night before. Upset by his brief amnesia, he visits a neurologist. There, he encounters a woman named Eunice who is assisting a wealthy patient as a sort of "memory aide." Liam is first intrigued by her job and then by her. With a lot of free time on his hands (and spurred by his recent misfortunes), Liam also reflects on his relationships and mistakes with his former wives and three daughters. Anne Tyler has written another novel that is perfect for book groups and those who love her eccentric character studies. It will be published in early January.
