Join authors Katharine Crawford Robey and Tracy Mikowski along with illustrator Zoe Williams for a collaborative book launch featuring their new children’s book Tor & Raven Are Friends on Saturday, November 12 from 1 - 3 p.m. at Horizon Books in downtown Traverse City. Robey will read the story out loud, Williams will give a demonstration of how she uses a computer to paint, and Mikowski will organize a drawing to determine who will take home the two special stones featured in the story. Tor & Raven Are Friends is based on the real-life relationship between a raven and a shepherd dog.
