NanKate, like you I can`t remember the title, but the book you mention by S.J.Bolton was, I think, her first book, and it was very good. I`ve finished The Wives of Los Alamos now, and it was okay, but I would have preferred it written in a more usual style, and to have gone into more depth with each individual family, or some of them anyway, enabling the reader to feel that they know who is being discussed. I also noticed the glaring error where the British toasted the Queen! I`ve just started Secrets of the Lighthouse, by Santa Montefiore, a new writer to me, but the book was the half price book of the week at Smiths, and looked good from the synopsis, so I`m giving it a try.
