A popular graphic novelist will be making an in-store appearance at Isotope Comics today.

George O'Connor is the Brooklyn-based creator of Olympians, a graphic novel series for young adults. The Olympians series features Greek myths retold by O'Connor in illustrated form. Later today, O'Connor will be at Isotope signing autographs and creating free sketches "for smiling kiddos of all ages," as Isotope owner James Sime puts it. So if you're a graphic novel fan (whether young or adult), head on over to 326 Fell Street. The appearance is scheduled from 5:30pm to 7pm today.
