And since today is apparently "not-on-sale-very-often" day, Frederick Ramsay's books don't go on sale very often either, and now here are three: two in his historical Gamaliel series, which I haven't read (yet), and one in his Ike Schwartz series, which I have read most of, and liked. All are $1.99 each, and discountable at Kobo US.
