This title was made available for free on Kindle, and since I share part of my first name with the title character (superficial reasoning, but hey, it works), and I love historical fiction, I thought I'd give it a go.
Meh. I couldn't get along with the writing style at all. It was very modern (and American) sounding for something set in the 1930s and 40s London. Bits of slang that weren't in common use then are all over the text. By throwing in references to Victory Rolls, Gone with the Wind and a bombing here and there, we are occasionally reminded of the setting, but it all feels quite "surface." Also, there seems to be plenty of food, especially sugar, during a time when rationing was the bane of everyone's existence. So much tea with "extra sugar because you've had a shock."
The characters are not very well drawn, unfortunately. I'd love to know just what made Charlie's mother the kind of woman that she is, and for a while there, I wasn't sure that Penny had an uncle at all. Disappointing.
But on to Charlie and Gracie. Gracie seems stunted (what 19/20-year-old hasn't learned the facts of life, if not from her mother, then from her girlfriends?) Further, find me a woman whose first night with her partner is nothing but bliss, and I'll show you a lovely bridge I have for sale. Gracie is an immature, whiny brat who gets an amazing amount of time off to live her life, and Charlie is a jealous jerk who doesn't want her to join the WAAF because there might be men around and he doesn't trust her to be faithful. But let's get married. Marriage between these two is the last thing I would recommend.
This was very easy to read, very fast and very innocent, by and large. It reminded me a bit of the romances that I read many years ago. I remember one swear word and (gasp), two characters spending the night together. More troubling were references to violence against a woman, and war injuries/deaths, although even these are dealt with fairly briefly. For those who are interested in this kind of story, this is the first of a series, so there are more to look forward to.
