Thanks to NetGalley and Simon and Schuster Children’s Publishing for the opportunity to read and review Lock & Mori: Final Fall by Heather W. Petty! So much intensity occurs in this book that I had to ponder and process my thoughts before I could write my review. Mori is still amazingly strong, intelligent and brave and she continues to be the biggest advocate for her brothers. When the story opens, Mori is imprisoned by Alice and her paid guards while her brothers are being used to threaten Mori into compliance. Mori has two goals in mind- 1. Save her brothers and 2. Rid the world of their father. Action and controlled anger take over the story as Mori does everything it takes to complete her goals. This final book in the Lock & Mori series completes a part of Mori’s life but ends with foreshadowing for her future. 5 stars for this mystery retelling of the relationship between Sherlock and Moriarty!
