What’s up with our wives and daughters?

Is it just me or is there a surplus in books these days about the wives and daughters of various men and their obscure occupations?  My point…

The Torturer’s Wife

The Memory Keeper’s Daughter

The Gravedigger’s Daughter

The Zookeeper’s Wife

The Heretic’s Daughter

Somebody Else’s Daughter

The Hummingbird’s Daughter

The Time Traveler’s Wife

Doesn’t anyone write about sons or husbands anymore?
