The diary format is unconventional yet effective, keeping the story’s pace brisk. The seamless connection between the initial setup and Emma’s tether to Ashley adds depth, making the unfolding mystery all the more engaging. Themes of guilt, identity, and the past’s enduring impact stand out,

with Emma’s journey offering a hint of redemption despite justice not being fully served.
