Following the fast-paced, action packed 'Red Queen', 'Glass Sword' dives back into the world divided by the colour of blood where tensions are the highest they have ever been.
Having managed to escape the Bowl of Bones by the skin of their teeth, Mare Barrow, Cal and the remainder of the Scarlet Guard are fleeing for their lives. Escaping to Tuck, a Scarlet Guard stronghold, Mare plans her next move - namely, to use a list she got given in 'Red Queen' containing the names of known newbloods - essentially, Reds with Silver abilities. It's a race against time as not only will Maven, the new king, be after her but will also be tracking down the newbloods in a bid to wipe out and deny their very existence, lest they threat the order of their world.
The story and action of this book rivals any dystopian fiction that has come out in the last few books - you will be turning the pages feverishly. The inner monologue of Mare, though, is not that distinguishable from many dystopian heroines. The 'I'm just an ordinary girl in extraordinary circumstances/I push everyone I love away/I'm turning into a monster' things are all very present and repetitive, despite their validity. I tended to gloss over these bits and focus on the mission to find the newbloods. I don't know whether it was the inner monologue that made me care less about Mare, but I tended to find myself caring more about the characters around her and their development.
There were several surprises, namely one shocker towards the end of the book that I did not expect to happen in this instalment, at least. If you are a fan of this genre, it's definitely something you would pick up and burn through in a few hours.
