⭐⭐⭐⭐⭐
Amazing! I say this after every book but I guess this is my favorite book of the series. I never once got boring reading this, I lost breath while flipping through the pages, my heart skipped many many beats. I never thought I would be this attracted to a "middle-grade" book.
The Lucy and Lockwood interactions... The Lucy and Skull moments..
There were some disappointments though. I was a bit annoyed by Lucy's decisions, she confused me a lot and the ending was also a cliffhanger. Thank God the 5th book is out.
