Roseland's Secret is a mystery set on Roseland, a remote island in the southern Atlantic. There, graduate student Andrew Ferguson researches why an unusual bird, the Roseland Auk, has many more males than females. Back in the States, his professor warned him that the island’s society is matriarchal, it retains pagan customs, and the women are off limits to outsiders. He ignores the professor's advice and falls for a beautiful islander, who is promised to the son of the "Penseythan", Jane Trevenna, the island’s head. Through his research, Andy uncovers the islanders’ dark secret. When he ignores the Penseythan’s warnings to stop meddling, he puts his life in danger.

The latest novel, Return to Roseland, chronicles Ferguson's adventures when he returns to Roseland two years later with hopes of wedding the beautiful islander he fell in love with two years earlier. But the islanders won't let him back in easily. Adding to his problems, his intended, Rose, is the prime candidate for the role of Queen in an ancient pagan rite on Midsummer's Day, a rite that requires her to be unfaithful several times over.

While Return to Roseland is a captivating story in its own right, reading Roseland's Secret first will enhance the reader's enjoyment of Sheffield's latest novel.
