In a Nutshell: Icelandic saga of kidnapped Irish princess, retold

Melkorka is the 16-year-old daughter of a medieval Irish king around 900 A.D. When she and her younger sister, Brigid, are sent away for safety before an attack by Vikings, they are captured by foreign slave traders and taken on a long sea voyage. Melkorka has always been free with voicing her questions and opinions, but now staying silent is what's keeping her safe, since the leader believes she has powers and doesn't want to incur her wrath. They go from Ireland through the North Sea to what is now Sweden, where her captor intends to sell them all as fine young virgins.

Well-written retelling with good major and minor characters. Napoli integrates lots of info about life in medieval northern Europe, and Ireland in particular. There's a simple map included for the visual among us, like me. There's also basic pronunciation guide for medieval characters like ð and þ, but a glossary with more complete pronunciations would be helpful.
Like in the Icelandic saga it's based on, this retelling leaves several important elements unresolved, which was unsatisfying to me but true to the story, and it also recreates Melkorka's situation and frame of mind more authentically for the reader, since she never found out either. Good read for fans of Napoli and realistic medieval fiction.
