This collection of excerpts appears to be from a novel titled "Angels of Destruction" by Keith Donohue, given the consistent chapter headings, narrative flow, and character interactions. The text follows Margaret Quinn and her sister Diane, initially focusing on Margaret's past and her daughter Erica, who ran away years prior, and then shifting to a mysterious young girl named Norah, whom Margaret takes in. The story intricately weaves supernatural elements and themes of loss, faith, and deception through the intertwining lives of these women, as well as a boy named Sean, who becomes involved with Norah's enigmatic nature, and Wiley, Erica's rebellious companion. The snippets hint at unresolved mysteries, including Erica's disappearance and Norah's true identity, and explore how these events affect the characters' perceptions of reality, memory, and belief.
