Last ones from me, a bit late I know. I'm afraid I've been lazy and copied blurbs from places like Goodreads and slightly reworded/sometimes shortened them.
Waiting for Sunrise, WIlliam Boyd. Set between Vienna in the 1910s, London in WW1 and the battlefields of France. Lysander is an actor and in Vienna seeing a psychoanalyst about a sexual problem who gets co-opted into wartime intelligence.
I got a bit befuddled by the intricacies of the spy stuff, and I found the writing about women/sex chauvinistic to the point I almost gave up. It's all about his pleasure and nothing to do with the women he has sex with.
Seashaken Houses, Tom Nancollas. Combines travelogue, history and memoir as the author visits and learns about seven of Britain and Ireland’s rock lighthouses. I'd never thought much about lighthouses, but they turn out to be fascinating in their own right as well as interesting in how they are embedded in history and culture. Engagingly written and pretty accessible even to a lay person who is not a buildings conservator like the author.
Winter Solstice, Rosamunde Pilcher. Five people's lives converge around a village and house in northern Scotland.
Gripping and absorbing in the sense of wanting to know how their lives will interconnect and how it will all play out. The relationships are touchingly done and it's quite humorous. Slightly spoiled though by the author's insistence that one of the protagonists, a woman in her very early sixties, is elderly and 'beyond the age for romantic love'. I kept expecting Pilcher or the character herself to kick over this trope, but no, it just seemed to be assumed. Also, lots of everyday sexism with people saying things like 'I can't just invite myself to their house for Christmas; it's not fair on Sarah' when Sarah is the wife but there is also a husband in the picture; the assumption being that she's the only one in charge/capable of cooking/cleaning/hosting guests. Great play is made of men choosing wine though 
I had to keep reminding myself that this was only written in 2000; although there are characters who work 'in the City' with 'computers', it largely read like a mid-century effort.
A Christmas Cornucopia by Mark Forsyth. A light and informative Christmas read.
War Paint: Madame Helena Rubinstein and Miss Elizabeth Arden: Their Lives, Their Times, Their Rivalry, Lindy Woodhead.
Fascinating, entertaining, gossipy, although oddly strays at points into dull (for me) details of sales figures and what happened at board meetings etc. Enlightening on these two genuinely extraordinary women and their empires, and simultaneously a fantastic overview of society in the period they both lived through.
Quite, Claudia Winkleman. I think others have not liked this on here. It IS fairly light (although she is heartfelt on things like personal confidence, friendship, embracing life etc, and writes very movingly about nurses in the section about her daughter's horrific accident – she doesn't address this very explicitly but it's obviously what she's talking about.) I liked this. If you like her humour and her voice on the TV/radio, you'll probably enjoy this.
Demon Copperhead, Barbara Kingsolver. As the world and their dog knows, this is a reworking of David Copperfield set in modern-ish day Appalachia. It takes in rural poverty and deprivation, the US opioid crisis, and the prejudice of the rest of the US and the world towards people in this part of the States, while also being a timeless coming-of-age story. The protagonist's voice, humour, outlook and (sometimes unintentional) insight are by turns hilarious, moving, devastating, heartbreaking and laser-sharp and always believable and alive; I really feel like I spent that time listening to him telling me his life story and his heart.
This is rich and multilayered, skilfully done, vivid, and utterly humane. It is a bit of a masterpiece.
