Treasure Hunters is really only readable as a serial installment of Bone, but it is a pretty good one, centered on intrigue in the royal city of Atheia. It ends with a gargantuan cliffhanger.
I suppose it is a sign of Jeff Smith’s skill at developing his fictional world and its characters that I have read each volume of Bone in fewer sittings than the last, even though their length and complexity remains consistent.
The end of the previous volume Old Man’s Cave made it seem as if the heroes had had a major victory, but Ghost Circles begins with almost overwhelming setbacks, and of all the Bone collections so far this one is easily the darkest in mood. Even a few scenes with the usually comical Ted the Bug are quite grave.
Magic was just something people liked to believe in, something they thought they could feel or sense, something that made everything more than just mechanical certainty. Something that made them more than flesh and bone.
