I am ever so grateful for the recommended review I received from The Bulletin of the Center of Children's Books. Here's some of what they said:
"... Vigilante has a nice way with subplots and solid daily-life details that bring the book particular warmth. Life in the projects, with a few criminals making things tough for the decent people, and with a vertical neighborhood of interconnected relationships created in the apartment building, is portrayed with candor and even some affection.
... the story is told with considerable appeal and accessibility, and kids won't have to lead the same life as Dellie to recognize her travai."
Thank You, BCCB! You've made my day.
