Four brand new listings for Batman and Scooby-Doo Mysteries novels have popped up on Amazon with an August 1 release date. Michael Anthony Steele will be writing all the books, but comic artist Dario Brizuela is credited for two of the books. The titles are "The Crazy Convention Caper," "The Case of the Cursed Crop," "The Chilling Ice Rink Escapade" and "Escape from Mystery Island." Each book will cost $6.95 for the paperback version and $26.65 for the hardcover version. There's no images available, so I have no idea if these are connected to the comic series just announced in any way.
Thanks to Deandre aka Scoobyfan4ever for letting me know about these!
