The Dragonslayer is the fourth book in the Bone series. It collects issues 20-27 of Jeff Smith's Bone comics. This volume marks the beginning of the second part of the Bone saga, entitled “Solstice”. The book was first published by Cartoon Books in its original black-and-white form in 1997. Paperback and hardback coloured editions were published in 2006 by Scholastic.
This volume follows the deepening hostilities in between the inhabitants of the valley and the Rat Creatures and their allies. Further secrets from Thorn's past are revealed, and Phoney Bone appoints himself the town dragon slayer. This one has a much darker tone than the previous books, evidenced in part by moments such as the one in which Thorn cuts off Kingdok's arm.
