This book offers an extremely compelling narrative with well-developed characters that fit their age and a thought-provoking plot that doesn't stray too far into the usal mystery tropes. The author's writing style is engaging without losing the pace consistency, keeping the reader hooked from start to finish without any noticeable slumps or pauses in the action. Themes are explored with depth and understanding, and the pacing is consistent throughout , even as points of view begin to diverge to account for the opinions of specific characters or situations. While some may find the book's ending somewhat predictable and not all that shocking nor initiative compared to similar books within the YA mystery genre, the overall experience makes it a worthwhile read with an enjoyable spin on an old classic like the locked room mystery.
