Moriarty's newest book is not "literature," and in any discussion, I could talk about some of its shortcomings. But, I thought it was quickly readable during winter days, a book that kept my interest.
It's a family book. The Delaney parents are ready to retire from the tennis academy that they have run for their entire marriage. All four of their grown children have been competitive tennis players, but now have mostly grown beyond that.
The family's balance becomes upset when a young woman shows up on their doorstep, apparently a victim of domestic abuse. The mom Joy befriends Savannah, and even lets her gradually become a member of the household. A mystery of sorts follows, as both Joy and Savannah disappear, and questions arise about whether any of the other family members could be responsible.
I've never been a tennis player, but I was interested in details about competitive tennis, and especially about rivalries that can be created. I thought the parent/child and sibling/sibling relationships were interesting. I didn't solve the "mystery" early, so kept reading to see where the plot was going.
So, see what you think. Moriarty's books, of course, have been adapted for movie and TV, and certainly continue to be popular.
