Plot summary

Meanwhile, Josua "Lackhand", brother to the king, leads a motley band of survivors after the disastrous events at Naglimund.

Princess Miriamele, having escaped before the siege of Naglimund, gets caught up in events that demonstrate the evil powers surrounding her father.

Princess Maegwin of Hernystir leads her people deep underground, where they discover secrets that may help turn the tide in a war thought to be hopeless.

Finally, a power rises in the North, but its true implications may not yet be fully revealed.

Reception
In Locus, Carolyn Cushman called the novel "an epic fantasy you can get lost in for days, not just hours".

Kat Hooper of fantasyliterature.com gave The Stone of Farewell a rating of 3.5 out of 5 and a mixed review, calling it "excessively lengthy" and saying it "is everything we’ve come to expect from a middle book in a well-written traditional medieval-style epic fantasy trilogy".
