I really enjoyed Throne of Glass, it's a strong introduction to a series and an easy book to read in a single sitting. Sarah J Maas certainly knows how to grab your attention and keep you hooked into the plot and the characters she has created. 
 There's definitely plenty of action and adventure, a bad-ass heroine and the world-building is incredibly intriguing. Throne of Glass actually reminds me a little of a Tamora Pierce's books, but targeted towards a slightly more mature audience perhaps, in terms of its creative scope and fantasy/fighting elements. It certainly captures that medieval fantasy vibe with a female-centric story line which I just loved. 
 There are a few plot-holes and it's not quite as good as I was expecting, but to be honest that was going to be next to impossible because this book has been so ridiculously hyped up to me. I'm also not really feeling the romance yet, it didn't feel particularly developed in this book so I'm assuming the chemistry becomes more prominent moving forwards. However I can definitely see why this is so popular and I'm keen to see where the series goes next.
