Absolutely, postively loved this book. It's about a pre-teen living with her great uncles for a summer. She discovers that their art, their passion, their towers are being threatened by gentrification (they didn't fit in with the new neighbor's idea of beauty, though they had been a neighborhood staple for decades). And so she mounts this amazing campaign to save them. Wonderful story of preservation, activism, and passion--for art and the community. So good that I've been meaning to write a letter to Konigsberg (who also wrote another favorite, From the Mixed Up Files of Mrs. Basil E. Frankweiler) and thank her for another amazing book.
