It's not every day that Northwest Arkansas gets the chance to host a personal visit from a glittering new literary superstar. But since Ayana Gray, author of the best seller "Beasts of Prey," is a University of Arkansas alumna, we're getting lucky. Gray will visit the UA campus this week, speaking to several student groups and giving a public lecture on Wednesday at 5:30 p.m. in the Gearhart Hall auditorium, with a reception to follow.
