I usually keep three reads going at a time.
Currently those books are the hefty biography of Alexander Hamilton that the Broadway play is based on, the newest Daniel Silva novel (The Black Widow) about the Israeli secret agent Gabriel Allon (my absolute favorite espionage series for many years now), and Our Souls at Night, a beautiful little novel by Plainsong author Kent Haruf which is being made into a movie starring Robert Redford and Jane Fonda.
What are you currently reading? Do you recommend it, or are you going to follow in the footsteps of the witty writer and critic Dorothy Parker? She once wrote that some newly published novel she was reviewing should not be cast aside lightly, but tossed aside with great force.
