Red Queen by Victoria Aveyard can be likened to a crossover between the Selection and X-Men. I personally love the X-Men and to my own surprise enjoyed the Selection. 
 I initially read this in 2015 and absolutely loved it but now looking back I found it was not as memorable as I thought it would be and I'm not furiously awaiting each instalment of the series. However it was an enjoyable read and something I would probably give another read in the future. The ending left me shocked and furious and filled with so many emotions. I thought it was a great ending to the book and set the scene for the second book quite well (I have since my initial reading of the book read the second but I have yet to read the third book in the series). 
 At first i thought it would be like 'Red Rising' by Pierce Brown since the whole red as second class citizens was something they had in common plotwise but the two books were very different. 
 Mare is a red...a second class citizens to the powerful silvers who have there unbelievable powers. However in the middle of the queenestrial Mare is found to have an unbelievable power of her own and is betrothed to Maven, brother to the heir of the crown. Mare has to struggle with hiding her red ancestry and trying to play the silvers at their own games.
