I would say that this is a solid 3-star read.
I really enjoyed the sense of place that the author evoked - the Henrietta Square apartments were luxurious and atmospheric, and the glimpse into the French Riviera in the book's final quarter was a real treat. The writing was accessible and easy-to-read, therefore rendering this book a great palate cleanser after reading the dense, literary (but very enjoyable) 'The Bee Sting'.
Some relationships curated between characters were warm and believable, like the short-lived one between Florence and Sean. Others appeared overly contrived, like the 'head over heels perfect' love story of Izzie and Sam. Maybe it's the cynic in me but, despite its brief nature, it seemed too good to be true. (Then again, the saccharine depiction of it could have been reflecting the 'honeymoon period' of the relationship.)
Two stars are taken off because, in spite of this being an enjoyable, quick read, the story had downsides for me. We are introduced to a 'secret' of Florence's; alas, this is never resolved. Some of the dialogue appeared stilted, as did the characters' actions. For example, on page 251, the protagonist throws a flip-flip off the wall in the middle of an argument with her lover, stating that she hates it because she expects it to outlive both lovers combined. Another cliché occurs shortly after page 200 when the caricatured bad guy Eli - the captor who has imprisoned Izzie within her own apartment - 'dangles the spare keys from under the mat in his hand' when she goes to look for them. Such scenes felt amateurish, eliciting an eye-roll from me. I also felt that Eli's departure from the story was farfetched and left a lot to be desired.
That said, the book was quite a feel-good Christmas page-turner. The addition of Gemma and her celebration of her newfound independence was refreshingly exciting to read, as was city life in the capital for someone like myself who lives down in 'the Sticks'. All in all, there was a lot to enjoy about this story, but I wouldn't say it made a lasting impression on me.
