Read this book last week. Easy read. The Arrivals (by Meg Mitchell Moore) is about a retired couple, Ginny and William, and their three adult children who all return home over the summer for a variety of reasons. Lillian comes home with 3 year old Olivia and newborn baby, Philip, after discovering her husband has had an affair at an office party. Stephen ends up getting stuck at home when his wife is diagnosed with placenta previa and she can't travel back to New York for the remainder of the pregnancy. And Rachel comes home after a long term relationship breaks up.
It's really just a story of a family and the messiness of families regardless of the age of your children. Good for a 'takes no brain power to read' type book but still enjoyable.
