I didn't love the writing as much as I did the second book. I thought from Jackaby to Beastly Bones had really grown in writing style but there were a lot of overused words in Ghostly Echoes that was bothersome and a few places where the action slipped a bit and I had to look back to catch up and make sure I hadn't missed anything. 
 The story did progress rather well though!! I love where this overall series arc is going and I always appreciate being able to look back and see what had been planned from book one that the reader didn't always know. 
 I'm also really glad that we got to know more about Jenny, her past, and her role at Augur Lane. 
 Looking forward to book four!! 
 Review as posted on The Book Addict's Guide 3/17/17: GHOSTLY ECHOES was a bit different all together with one of the main characters being involved in the mystery instead of someone from the outside. I really loved how much more personal the mystery became -- to Jackaby and Abigail as well as the reader -- and where the whole series went! Things really escalated in this book and I really appreciated how so many things came full circle here. 
 The friendships in this book were stepped up even more and I love how much tighter this group got! The different elements in this mystery were also top notch and I think this was my favorite book of the series!
