Loving Frank is the book my book club in California read this month. I miss them - we almost never read anything I liked but the company made up for it. I give Loving Frank a 'B-' because it was well-researched and fairly well-written, but I’m also being generous because it was mega boring, like watching a mushroom grow.
Then again, although I'm an avid reader I hardly ever like book club books that everyone else in the entire world loves so you might want to take my advice with a grain of salt. For example, I didn't like "Water for Elephants" so you can use that as a barometer to decide whether we have compatible literary taste.
Here is a very high-level plot synopsis of Loving Frank, which you SHOULD NOT READ if you hate spoilers:
"Married woman with unusual and somewhat irritating name (Mamah) and 2 children leaves family to shack up with Frank Lloyd Wright - a bit like Tolstoy's 'Anna Karenina' (now THAT was a great book), only without the character development. Husband pretty decent about it all and she gets visitation rights with her kids. Unfortunately, crazy ass hired hand kills pretty much everyone except Frank with an axe and then burns them to ashes, including the kids. Tearfully writing her eulogy, Frank justifies the decision she made to leave her children for the sake of love by pointing out that they were with her when she died. Frank goes on to design famous buildings. The end. "
So, I didn’t love it, although it was still better than She’s Come Undone.
