With the end of Gilr at Midnight, we left Echo and her companions in a strange situation. After the discovery of her true nature, Echo is hiding in London. The Avicens, after Ruby's death and her own actions, aren't her home anymore and the Drakharinare searching for her. Ivy, Jasper, Dorian and Caius aren't that okay. 
 The second book is quite full of improventes but The Shadow Hour is still not a ya masterpiece. Some things are the same as before. There is still Echo with random words that passes trought her mind at the not most appropriate moments. The travel feeling is still there, along with a bit of humor and nerd quotes. 
 Probably, what I really like of Grey's books is the ability to bring to life unclassic fantasy races, just like Avicens and Drakharins, but also to use unrrated fokloristic figure and creatures. But at the same time that it's a bit of a negative point. Let's keep the kucedra ad an example. I didn't know what it was and it's an actual mythogic figure, so not somethine that the authore made up for the book. I've no problem to made few research and find more things about the kucedra, but since it's something "not made by author", I think that a bit of explenations or notes at the end of the book could be a great thing. Also the Ala is quite ancient and so is Caius, so the could talk about it as much as they want. 
 Anyway, I really like this second book. It was a light read, quite funny and I don't even know why - since I usually don't do that - but I shipped the characters. I want to be drowned by ships in the thrid and final book. 
 I also liked the romance, but I'm not talking about Echo, Caius and the semi-trinagol that was created with Rowan. I didn't care a bit. But I loved Jasper and Dorian. Seriously. I loved them. And my ship even survived. I was so freaking happy. 
 Also, I really hope that one the minor characters that was introduced near the end, Helios, will play a major role in the futuro. Plus I ship with Ivy. 
 This time I fangirled. And that's perfectly sane. 
 I also started to like even Altair and I was waiting form him and Echo to hug. I can't say more beacuse it's spoiler, but the authore was kind happy to play with my feelings and to kill my soul. So, I think that thi was also a wasted occasion. There was so much potential and the end is: nothing. If you will read the book, you will understand. Also Tanith didn't gave such a great impression. 
 Some solutions were quite cliche but they didn't really bother me because the were integrated well withing the story and the characters. There was a lot of drama, especially with Rowan - jeez, wake up, boy! - and with Echo questioning her true nature which was kinda stupid since she's a grown up lady that can take quite care of herself and that know her own soul and mind.
