The Princess and Curdie by George MacDonald

The Princess and Curdie is the sequel to The Princess and the Goblin by George MacDonald. It’s been a year since the Princess Irene and Curdie first met, and a year since the goblin incident and all appears to be going well in the Kingdom. Or is it? After a visit from Irene’s great-great-grandmother, Curdie finds himself on a mission to save the kingdom, with a rather strange companion in tow.
