ugh the FEELS !!! ok well someone in a review somewhere totally spoilt one of the big twists for me, so DON'T read thru too many like I did lol. Definitely took the surprise out and colored my reading experience differently than I expect other readers'. 
That being said, this book has it all. Great laughs (Geraldine & Tyler, gotta love 'em), forbidden romance (Blue & Lance, see more Darius & Tory action), more mysterious clues, and now we start to explore more of the Shadow realm and its magic. 
A lot of readers seem to dislike Tory in this one - to be fair, she is VERY stubborn, but I can see where she's coming from. Plus, you can't expect to write characters who don't have flaws and figure everything out and make all the right decisions, what kind of series will you have? Nothing it'll be three pages and done. Conflict, conflict, conflict!!
Can we talk about how much I fell in love with Darcy & Orion? Like.. student-teacher, older man issues aside LOL but really their love feels so pure and beautiful... ugh it hurts.
I do have many questions (I wanted more info from the Palace!!!) and the ending is the BIGGEST, WORST cliffhanger YET of the series so you know what that means... Gotta start #5 as soon as I finished writing this review.
