After three weeks, Vassula Ryden’s new book, Heaven is Real But So is Hell, shot up to Number One on the BarnesAndNoble.com Top 100 list, and the book wasn’t even in stores yet. Moreover, not a single advertisement has been run. Ms. Ryden will be in Chicago on Wednesday, March 27, 2013, for a 7 p.m. book signing at the Barnes & Noble Bookstore at 297 Oakbrook Center in Oakbrook, Illinois.
