Nope. He's a bigwig with Archie Comics and creative force behind Riverdale. He writes two excellent books hampered by infrequent publication due to his schedule. If you aren't reading Afterlife With Archie and Sabrina the Chilling Adventures of Sabrina you're missing out on some good stuff.
Afterlife with Archie is the best zombie book I've ever read. Its too bad the publication schedule is so infrequent. I liked much of his FF run, but, I never got the sense he could do an epic scale cosmic type adventure deserving of the four.
