Book II deepens the series' themes of identity, civic pride, and the power of words.

Standalone Holiday Title
Eleven days before Christmas, ten-year-old Angelica discovers that Dickens House, a Manhattan home for found families, will close unless someone acts. Refusing to stand by, she takes a simple stand on a New York City street corner and sets in motion a chain of events that connects strangers across Hell's Kitchen. As Christmas approaches, a man carrying long-held secrets, a first-day intern, eccentric collectors, a mysterious dog named Reni, and an unexplained white feather become part of a story about courage, community, and the power of paying attention in a city of millions. Set in contemporary New York during the holiday season. A heartwarming middle-grade novel celebrating found family, kindness, and the impact one child can have on the lives of others. For ages 8–12, with strong crossover appeal for adult readers who enjoy holiday fiction and stories inspired by the spirit of Charles Dickens and O. Henry.
