Frankie must navigate the challenges of looking after Amelia, a disruptive guest whose presence threatens to unravel her carefully managed life. Frankie's mother has agreed to host Amelia, a friend's daughter, for two weeks, placing the responsibility of entertaining and supervising her squarely on Frankie's shoulders. Amelia's tendency to attract trouble, despite Frankie's efforts to shield herself and her space from it, creates constant friction and anxiety. The narrative explores the dynamics of forced cohabitation and the struggle to maintain order when an unwelcome, chaotic element is introduced into one's personal environment.

The premise sets up a relatable scenario for young readers dealing with unexpected houseguests and the ensuing disruption to their lives. The narrative likely focuses on Frankie's perspective as she grapples with the responsibilities thrust upon her and the social awkwardness of managing Amelia's troublesome nature. The story appears to explore themes of tolerance, managing expectations, and the complexities of interpersonal relationships within a domestic setting. It is probable that the resolution involves Frankie learning to cope with the situation and perhaps finding a way to coexist with Amelia, or at least survive the fortnight.
