The last two bios I read were last spring and summer, and both were on Reagan. One was "When Character Was King", I think, by Peggy Newnan. The other was by Mike Deavers..? Both were good.
I like John Grisham -- but I read his all in one sitting, so it gets expensive to buy them.
The most recent book I've read was by Cassandra King (Pat Conroy's wife) -- "The Same Sweet Girls." It was just okay.
Each time my wife and I go to Australia, we bring back Aussie historical novels; two of the best I have read are by Evan Green, Kalinda and Adam's Empire, a two book series.
I had to buy Kalinda from used book section on Amazon, prices all the way up to $107US per copy.
