The middle book in Sherwood's mid-80s buccaneer series, "Windsong" moves the action along. At the end of "Lovesong," the first novel in the trilogy, Carolina Lightfoot and Rye Evistock have been "wed" on Tortuga and anticipate repeating the ceremony legally at her home in the Tidewater. Of course fate has other ideas. The first part of the book happily punctures those expectations, while spending time once again with Carolina's eccentric, quarrelsome family. After that, the action moves to London, where things threaten to come apart--both for the couple and for Sherwood. Rye's past comes back to haunt him in multiple ways, which culminates in the Azores. Sherwood takes a great risk with what--to her, unlike her contemporary Rosemary Rogers--was previously a guiding principle: the monogamous bond between the central couple. It doesn't quite work, at least it didn't for this reader, no matter how much Sherwood and Carolina/Rye try to explain it. Despite that sour note, Sherwood sets up everything for a conclusion in "Nightsong," the third book. Not filler material by any means, "Windsong" is enjoyable despite its potentially fatal flaws.
