This is one of those Harlequins that is *really interesting* but not particularly fun -- in part because I think Farnes is very realistic about the impact that Alex's past has had on her, and there is a lot of unhappiness in Alex's life on the way to her HEA.
As for plot -- it is a much longer arc than the usual Harlequin one of this period, which was also interesting! Alex Paul grew up in a dysfunctional family, but thankfully her friend Cicely's parents were great people who gave her enough stability and structure that she was able to figure out what she wanted in life -- which is to be a fashion designer! As the book begins, Alex is working for another woman, but she's ready to start her own business, so she very deliberately picks out a man who she thinks is rich enough to provide capital and intelligent enough to do it as a business investment rather than as a personal relationship. The man in question, Charles, is a handsome playboy but also a good guy in all the important ways -- he sees that Alex is talented and ambitious and likely to succeed, so accepts the terms of their relationship and enjoys a friendship with her while helping her business grow. As the years go by Charles falls for her, and she eventually falls for him, and they have a wonderful romantic kissing scene, but when they talk over their future the next day it's a disaster -- she won't be his lover, she wants marriage, and Charles isn't interested in marrying anyone, he likes being independent. Charles tries playing a waiting game, and I was impressed that Farnes never has him making the first move -- he's just there, continuing his financial support of the company without any strings, and indeed, eventually Alex seeks him out again because she's so attracted -- but although she's tempted to change her mind, she eventually comes to the conclusion that EVEN THOUGH nobody else might judge her, she wouldn't be able to live with herself.
Meanwhile, Alex has spent time visiting her friend Cicely, who is now happily married and living in the country, and Cicely's neighbour Terrence has fallen hard for Alex -- he'd love to marry her and wants her to keep her career, saying she could come down to his farm on the weekends and live in London working the rest of the time. Alex appreciates his many sterling qualities but she's just not in love with him, plus she thinks that he'd end up lonely and unhappy with a wife that he only saw on the weekends, no matter how much he wanted to make it work out. Eventually, of course, there is a HEA in which Charles realises that he'd rather have Alex than keep being a bachelor, and so they will have a wonderful companionate marriage plus (without question) she'll keep her career.
What fascinated me about this one is that Farnes is walking a line around pre-marital sex here that is not so surprising for 1968 (although still rather surprising in a Harlequin of the period), but is a lot more surprising to me for 1956, when this was first published by Mills & Boon! Alex has decided against premarital sex *for herself* but neither she nor Farnes' narrative voice condemns the characters who decide differently. Alex doesn't think she's better than Charles, or better than the women he sleeps with, she just thinks it would be immensely wrong for *her* -- and part of why it would be wrong for her is that she and Charles would have to pretend not to be a couple, and she feels like the sneaking around and lying would eventually change their feelings for each other.
So, yes, interesting! But not *fun* so I will probably eventually free my copy to the wild, because I can't really see reading it again.
