Assassin's Blade, The
This was one of the most thrilling and heartbroken book I've read yet. It gave me so much feelings and as I turn page after page I couldn't stop. I just simply need to know what happens (I actually already knew what was going to happen and I was dreading towards the end BUT it was a really good book and I couldn't help but feel like I was part of the scene) This book is about when Celaena was with Arobynn and back at the Assassin's Keep. She went through this mission with Sam which they had to do something risky. Celaena then went far away a few chapters later to train with someone. When she came back to the Keep something changed between her and Sam and one thing led to another. The ending is something that's not easy to handle and just plain out sad. We learn a lot about Celaena's background while she was still Arobynn's protegee. Definetely something you should read before reading the actual first book which is: Throne of Glass (ToG). Though I read this series in the wrong order, I just really love Sarah J Maas's world she had created. My new favorite author at the same time favorite series so far.
This is a book of five short stories that take place before Throne of Glass and really helped get me into Celaena's head. Since I read it after reading the rest of the series, it helped with back story on the characters from Celaena's past that she grows to love or hate over the course of the series. There was a ton of great action and adventure and romance and despair. This book is beautiful and the last story will gut you.
