Rachel Pomerants is Definitely one of my favorites. I just finished “Wildflower” – absolutely amazing. There’s so much you can learn from her books. I’ve read countless times “As Mountains Around Jerusalem” and “A Time To Rend, A Time To Sew”.
As for suspense novels (which I usually feel empty after reading, so I don’t do it often) Chaim Greenberg is certainly the best. His latest “Mexico Files” had me reading it almost in one shot. Both, his first book, “The Will” and this are well written and truly fascinating.
