'This is one of the most perfect boulders I've ever seen in my life,' says Nalle Hukkataival, of 'African Star,' his latest find in Swaziland. The only problem is that it might be impossible to climb. So begins the last day of Nalle and Jimmy Webb's exploratory trip to southern Africa. They've climbed some amazing boulders but Nalle's new discovery is that rarest of things, a king line. The love affair with the über-project is doomed to be short lived however as Nalle faces a race against time attempting to free the line before he is due to return home.
