 Blue Lily, Lily Blue has really curved my feelings for this series. The first book, The Raven Boys, was pretty good. I liked it but seemed to be sitting in the minority because I wasn't initially BLOW AWAY. The second installment, The Dream Thieves, was so much more entertaining and I adored it. I have a soft spot for Ronan, so there is that. 
 THIS BOOK. *sigh* Was it the Gansy and Blue scenes? (PROBABLY) The tremendous growth from Adam? The countless secrets that are uncovered and plot points brought to light? Maggie's ability to have me root for a serial killer? All of these? I DON'T KNOW. I just know that I have undoubtedly fallen in love with his series. 
 I have always been a fan of Maggie's writing, regardless of the overall punch of emotions from the books. Her books are so imaginative, unique and unpredictable. You never know what is going to happen, and once you figure something out, another mystery is formed. Her ability to keep on my toes and guessing is just one of the many things that keeps me coming back to her books. 
 Another thing about her writing - she is a master at cliffhangers. If you thought that the previous two books had a cliffhanger? THINK AGAIN. 
 All the characters in this series are so remarkably unique. Even the secondary characters are so well-developed and fleshed out. I can't name very many books with so many characters and POVs that keep me so entertained and done so well. Their relationships are complicated too - but in a good way. Especially between Gansy, Adam, Ronan and Blue. Gansy & Blue. Gosh, those two together give me all the feels. 
 Overall - 
 I loved it. Blue Lily, Lily Blue is the best book in this series so far. I am definitely hooked. I highly recommend this series.
