Read Together Diamond Bar (RTDB) is an annual program that takes place in April to unite people of all ages and backgrounds by reading the same book. RTDB starts with the idea that when a city opens the same book, it closes it in greater harmony. The Friends always select three books for RTDB: a book for adults, another targeted for young adult readers, and a third book suitable for children, with all three books sharing a common theme. RTDB is based on the concept of One City, One Book where everyone in the community reads one book and then participates in book discussions and various activities at the library.
Students ages 13-18 are encouraged to write an essay about how a book changed their life. More details on the annual essay contest can be found here.
Finally, RTDB concludes with a presentation and discussion by an author. Each year, the author discussion event that concludes RTDB draws enthusiastic crowds, a fitting conclusion to a month-long series of opportunities for readers to learn, share and celebrate their joy in reading.
