Actual rating 2.75 stars.The mythology of Sirens is interpreted in this young adult centric world of partying and pretty dresses. The work of a Siren is isolating and deadly – calling sailors to their death. But as Kahlen begins to question why things are as they are, will it mean her death or the destruction of the things she holds most dear?This was a quick and easy read. It drew me into the narrative well enough and kept me engaged, but wasn’t what I would call outstanding. I liked how it explored the themes of control, abuse, loneliness and depression. The mythology is solid, but there is something about this story that I can’t quite identify that it missed. Maybe it was the frozen maturity of the Sirens – who are meant to be well past 50 years old, yet still acting like superficial teens. The characters felt underdeveloped.There was a wide range of ethnicity, but we don’t see their culture being represented. It felt mostly white-washed.The Sirens were allowed to have some semblance of a life outside their duties demanded by the Ocean, but we only hear about clubbing, shopping, reading, and painting. I would go nuts if that was all I was doing for 80 odd years. I just feel like there was so much missed opportunity for the girls to grow and develop... or heck even use their powers in a more subtle way to expand their worldly view. This book felt like it was written by, and for tweens. There wasn’t a lot of complexity in the characters or with the plot.The romance felt sweet, but fell under the trope of ‘instalove’ for me. I would have liked to see it develop a bit more and see them falling for each other for more than their looks and one or two superficial interests.Kahlen wasn’t a particularly engaging protagonist. She’s pretty much a goody-two-shoes in the Siren stakes. She also does not engage much with the other Sirens, or with the general population; but instead whines about how unfortunate her predicament is, how guilty she feels for luring many to their deaths. It would be a great starting point for an interesting character arc, but unfortunately that is all she does. I was hoping to see her try to make amends for her actions. Challenge the Ocean harder, explore the reasons why she has to do what she does, seek help to deal with her guilt and grief. But all in all she is an incredibly passive character.Cass’ writing style is somewhat melodic, but given that the Sirens travel the globe, visit exotic places and explore the ocean, I was expecting a lot more atmosphere – a balance of the beautiful and the terrifying. There was no mention of the creatures living in the ocean, of pollution, of the wonders of the deep. I felt let down. But the word choice and sentence structure is lent to that younger end of the YA demographic, so I can see them being able to digest this easily, and if enraptured by the fantasy of looking pretty, having little responsibility, going shopping and clubbing and staying young for 100 years, they will enjoy this.I still don’t understand what the thing about the Ocean constructing prom dresses for the Sirens out of salt was all about – was it to keep modesty for the characters given the target market? The other thing that got me was an 80 year old woman, with a big chunk of life experience, still did not know how to style her hair or put on makeup. I mean come on!Despite the glaring contextual issues and plot holes ‘The Siren’ is a pleasant and easy read that was nice escapism, but it felt a little flat and underdeveloped. But having discovered that this was Cass’ first attempt at writing a novel, and had been passed on by many publishers, and only later published due to the popularity of The Selection series, I  can understand this novel a little better in this light. But maybe the publishers should have done a better developmental edit to help Cass really shine and keep an upward momentum in her catalogue.
