We would like to thank Lynne Potts, a local South End author. Ms. Potts read excerpts from her new book, A Block in Time: A History of Boston’s South End from a Window on Holyoke Street, last Thursday evening at the SEHS. After the reading, Ms. Potts answered questions and signed copies of the book for attendees. A Block in Time is for sale at the SEHS office, and on Amazon.
