The Assassin's Blade

This book is a collection of relatively short stories showing us the “origin story” of Celaena and I will highly recommend you read it after book 3 of the series - Heir of Fire.

Say what you will about Sarah J. Maas, the woman knows how to write addictive books and just when you think you've got her all figured out, she goes and sneaks in some subtlety.
I quite enjoyed this collection even though Celaena was fairly unbearable for a big part of it. But given that this is pretty much the beginning of her character arc, it's rather understandable. And we did see hints of improvement.
I am ashamed/happy to say that this book made me cry and experience some serious dread and sorrow. The hours where Celaena is waiting for Sam to return but he doesn't and you know he never will... this part killed me. I felt like it was I who was waiting and I have rarely experienced such sorrow from a book. It was masterfully done.
Great book!
