Publisher's summary
"Super Team" part five. Well, we tried to warn you. Bigby and the North Wind finally threw down and poor Bigby didn't stand a chance. We would have loved to come up with some clever, magical way our favorite Lord of Wolves beat his dad in a knockdown, dragout, mano-a-mano fight to the finish, but there was simply no way. Sorry. We tried, and we couldn't do it. Oh, also the barrier keeping Mister Dark out of Haven falls, leaving the kingdom entirely unprotected from his wrath.
Plot
North Wind strangles Mr. Dark, takes both of them into his world, and plans to kill the both of them. Both North Wind and Mr. Dark fall into his magical box which kill them both, the box was held by Bellflower. North Wind sacrificed himself so he couldn't kill his grandson. Everyone is told by Bigby that North Wind most likely killed Mr. Dark. Rose Red is told by the unknown magical creature that made her face the world again that Rose Red has many possible outcomes in the future. Bigby questions why is father did something so noble, but one of North Wind's servants tells Snow and Bigby that one of their children will have to be the next North Wind.
