Les Loups de la Calla - La Tour sombre, tome 5

Roland and his gunslinger friends, now inextricably linked, continue to walk along the Path of the Beam. This is where emissaries from the valley of La Calla - a defrocked priest with a turbulent past, three farmers and a giant robot - come to find them and ask for their assistance: the Thunderwolves, monstrous creatures that tear children from their families to send them back lobotomized, are decimating the community. Will the gunslingers realize that if they embrace the cause of La Calla, they could well be closer than they think to their ultimate goal, the Dark Tower and its mysteries?
