In short: Unfortunately, I had a hard time connecting to the characters and relationship in Radiant Shadows by Melissa Marr. But at least there was no Keenan! 
 Radiant Shadows is the second departure from the Aislinn-Seth-Keenan storyline in the Wicked Lovely series (the first one being Ink Exchange) while still being a continuation of the story. If that makes any sense at all. Radiant Shadows features halfing Ani, who we learn about briefly in Ink Exchange, the advisor to the High Queen, Devlin, who we learn about briefly in Fragile Eternity, and a completely new character, Rae, who is a dreamwalker. 
 I was pretty tolerant of the first departure from the main storyline in Ink Exchange (Wicked Lovely #2), I think because I hadn't become as invested in the main characters at that point, but after reading Fragile Eternity (Wicked Lovely #3), I found that I didn't have very much patience for these new characters. While Marr does a fairly good job at tying in this book to the overarching storyline, I couldn't help but feel like I just wanted to get back to the main story with the main characters. I think it's for this reason that I had a hard time connecting to any of the characters. Also, the relationship between Ani and Devlin was just sort of random and felt inauthentic. There was no real buildup to their relationship. 
 I hesitate to mention this, but I have one nitpick with the plot that just won't stop bugging me: I really wish Marr had taken the time to understand how the Sleep Cycle and REM Sleep works. Or maybe she does know but she just chose to ignore it. At any rate, there were certain scenes involving Rae, the dreamwalker, that just didn't work for me because they didn't have at least a basis of fact. It might be unfair of me to nitpick to this detail but unfortunately, it did impact my enjoyment of the novel and simple research on Marr's part could have corrected this. 
 The ending was the saving grace of Radiant Shadows; I really liked the direction and advancement of the plot at the end. It sets it up perfectly for the final in the series, Darkest Mercy! Another thing I really liked was the further look into the mythology of the Dark Court, and along with that, Niall and Irial's relationship. Also a plus: no Keenan!
