I had high expectations when I read the blurb and saw the stunning paperback cover containing lots of gold, plants and beautiful flowery details. The story had a promising timeframe (a sweltering hot summer in the 70s) and revolved around a group of teenage girls taking pictures of each other lying in the river dressed up as Persephone or Ophelia. Combine that with family secrets and a mysterious death of one of these "Ophelia Girls"... I was hooked. What the story delivered, however, were dull conversations between teenage girls, lengthy and often irrelevant descriptions, and a very slow plot that didn't turn out to be so exciting or mysterious after all. The revelation of the mystery was very underwhelming to me.
I was pleased to see that the story included references to art (Waterhouse, Pre-Raphaelite paintings), literature (Shakespeare's Hamlet and Ophelia) and Greek mythology (Hades, Persephone). These references tied into the plot, but there was nothing more to them than that. Don't expect depth or profound commentary on any of the themes either (e.g. grooming, motherhood, family dynamics, identity and young womanhood).
I finished the entire book (358 pages), but I didn't enjoy myself in the process. None of the characters were likeable, for example. As a result, there was no point to an epilogue in my opinion, because I couldn't care less how the characters were doing. The book focused a lot on descriptions of the group of girls in the 70s and Maeve in the 90s pretending to be Ophelia girls, which became repetitive and boring. I also figured out the mystery early on the book (the fact that Ruth didn't love neither Stuart nor husband Alex and had something against the scent of their perspiration gave it away for me). I wish there was something positive to be said for the climax and ending of the book, but to me it came across as overly dramatic and the revelation of other secrets were underwhelming.
Based on all this, I personally wouldn't pick up another book by Healey any time soon, but I can recommend The Ophelia Girls to someone who enjoys lengthy descriptions of who says what (no matter how mundane) and what the surroundings look like in minute detail. If characterisation isn't very important to you, you're OK with having no likeable characters in a book, and you don't mind switching perspectives per chapter and a slow, meandering plot, I'm sure you'd enjoy The Ophelia Girls.
