Author Katherine Paterson is the next speaker in the Leslie Riedel Memorial Lecture series at the Concord Free Public Library. The talk will take place on Saturday, Oct. 21, at 7 p.m. and is geared for audiences age 8 and older. The lecture series was created in memory of Leslie Riedel by her family and friends so that young people could meet some of their favorite authors. Paterson has written more than 30 books and has been awarded the Newbery Medal two times, the National Book Award, the Hans Christian Andersen Award and the Astrid Lindgren Memorial Award. There will be a reception following the talk, and books for autographing will be available for purchase.
