Linus’ narrative makes for a gripping page-turner from the very start. The effectively crafted atmosphere of suspense is maintained throughout the novel, fearful tension saturating every page as Linus struggles to hold onto his sanity, even when his hopes are repeatedly crushed. The Lord of the Flies-esque scenario that develops within the bunker is a clever examination of the human condition, seen through the eyes of an endearing but troubled teenage boy with an authentic voice. Although, while the bunker is merely an intriguing backdrop for a primarily character-driven story, I still found myself disappointed with the lack of resolution in the plot, which was, until the end, building toward a promising climax— a climax that never really happened. The outcome of the story is implied, but the puzzle built throughout the novel is never actually solved. What was a tantalizing mystery was left disappointingly murky, the identity and motives of Linus’ kidnapper remaining unknown. Perhaps this ambiguity was a part of the message that happy endings are unrealistic, but all the loose ends could have been wrapped up much more soundly while still retaining the same impact. Buckle up for a harrowing, fascinating journey— but don’t hold your breath for an exciting conclusion.
