   Summary

   Bob struggles with the blackouts that leave him disoriented, haunted by nightmares, and unsure of where he’ll wake up next. After finding himself in Walker’s room without remembering how he got there, Bob is forced to confront not only the gaps in his memory but also the unsettling closeness of his teammate. As training with Walker blurs the line between discipline and something far more personal, Bob begins to question whether his shadows belong to himself… or to the Sentry.
