Wild Sign

Wild Sign is the thirteenth book in the Mercy Thompson series, and while each book has a self-contained mystery, the overarching character development and relationship arcs build significantly from previous installments. New readers will miss much of the emotional depth and character history if they start here.

Wild Sign is part of the Mercy Thompson series, which is set in the same universe as Patricia Briggs' Alpha and Omega series. While the two series feature different main characters, there are occasional crossovers and shared world-building elements that enrich the overall experience for readers familiar with both.
