This week, Jamie Tyler, author of the “Cowabloga” Ninja Turtles blog, is BACK to talk about the most convoluted, frustrating, fascinating and satisfyingly unsatisfying Big Chapter Book I’ve read in a while: “The Berenstain Bears and the Perfect Crime (Almost)!” Yes, get that parenthetical in there; it’s important. Jamie and I work ourselves up to a fever pitch as nothing makes sense, adds up or resolves in any way resembling logical or even dramatically resonant. It’s amazing. And I love it.
