Island of Wings by Karin Altenberg

Putting their marriage and sanity to the test, the newlywed MacKenzies sail in 1830 to the isolated yet hauntingly beautiful St Kilda islands on Scotland's outermost Hebrides. Neil's evangelical mission is clear: Challenge the native's pagan ways and find atonement for his own past sins, while his devoted wife, Lizzie, searches for a sense of purpose and belonging in a new world neither truly understands.

Island of Wings, Karin Altenberg, $23.
