If you have any spare time between 6 p.m. and about 7 p.m. tonight, we highly suggest you go to the Penn Bookstore (3601 Walnut St.) and hear Wes Moore talk about his New York Times Bestseller “The Other Wes Moore: One Name Two Fates.”

The book contrasts the lives of one Wes Moore, the author, who was a Rhodes Scholar, combat veteran, White House Fellow, and another Wes Moore, who is serving a life sentence in prison for murdering an off-duty Baltimore police officer. Both men grew up in the same neighborhood and are two years apart in age. The book is about how two lives that started so similarly could end up so differently.

“The chilling truth is his story could have been mine,” Moore has said. “And the tragedy is that my story could have been his.”

Here is a video clip of the author talking about the book:
