Loved the overall premise of this one and it was very well done! I definitely felt growth and more cohesiveness from the first book to this one with a great lead in to the third (which I now want to pick up ASAP but have a few more things on the TBR before I do)! 
 Review as posted on The Book Addict's Guide 3/17/17: I started BEASTLY BONES right after I finished JACKABY because the first book was just so enjoyable and a breeze to read! I thought BEASTLY BONES stepped it up even more and that William Ritter's writing really improved, not that I thought JACKABY was lacking, but it felt more mature and more put-together. 
 I loved the fantastical element in this book and I won't give it away because it was a super fun reveal for me but it was a creature that I was so excited to see, and even that had a turn of its own. The characters handle the situation adeptly, as always, and the mystery was a hoot! 
 One thing I actually didn't like was the appearance of some secondary characters that were immediately eliminated in this book. They had such a heavy focus in BEASTLY BONES and it kind of felt like a waste to get to know them for such a short time only to never see them again. There was also a bit of repetition of terms and words in this book that I started to notice a lot (I didn't need to read "indomitable" 20 times) so that was a little frustrating but I thought the mystery was even more exciting than the first book and it took a different turn as well!
