Hermetic Library Fellow T Polyphilus reviews Bone: The Dragonslayer [Bookshop, Amazon, Publisher] by Jeff Smith, book 4 of the Bone series.

Phoney Bone is the primary actor in this segment of the Bone story, although for all his scheming, he is out of his depth, as usual. It is unclear until the end of the volume, whether he is accidentally helping the heroes, or unwittingly harming them. Thorn advances toward maturity and purposefulness, and not a minute too soon. On the whole, this stretch is somewhat tense and plot-heavy.
