The Heart's Blood Arrow by Kai Butler

adventurous challenging emotional funny mysterious tense medium-paced

5.0

Another incredible installment in this fabulous, and addictive, series!

I absolutely adored "The Heart's Blood Arrow". I didn't think it was possible, but this fifth book is even more action-packed and heart-stopping and explosive than the previous ones. It's also slightly less gut-wrenching than the previous two books, since Parker's slowly letting go of his guilt, his grief is under control and for once, he's managing his insecurities about being worthy of love and affection quite well. 

We've seen so many sides of him: the barely functioning adult, the manipulative fae, the reckless, quasi-suicidal kickass, the insecure and broken orphan, the grief-stricken son, the protective lover and brother... This fifth book allows us to glimpse another side of Parker: the chaos gremlin. 
This book is decidedly more light-hearted, and Kai Butler blesses the reader with Parker's many, hilarious attempts to ask Nick to marry him, his hilariously chaotic jealous streak (ft. his one attempt at running to show the world how well-matched he and Nick are) and his highly entertaining, and disastrous, interactions with the King family. 
I loved him so much here, and I absolutely adored how much his relationship with Nick has grown and gotten stronger. 
I also managed to fall in love a tiny bit more with the absolutely compelling cast of side characters: Sugar needs to protected at ALL COSTS; Laurel is such a badass; Zahide and Avila can step on me any time; Tate is the ultimate Daddy Materialâ„¢; and the whole wolf pack vs the feral brownies debacle had me CACKLING. 

Plot-wise, I have to admit I, surprisingly, kind of missed the fae courts machinations in this one: I found the old gods and their appearance really fascinating, but I'm hoping we'll get some answers about what the hell is happening in the Summer Court and in general, I really want to see Parker's role as Windrose expanded. 

I'm beyond curious to see what will happen next: I can't believe I've managed to devour these books in so little time, and I'm desperate to time-jump myself ahead in the future so I can devour the last (I'm already preemptively crying because the end is so near 😭 ) two books in this series.
