Briggs has created the perfect tie-in to her Mercy Thompson series. Hunting Ground
is the second Alpha and Omega book and expands the supernatural world Briggs introduced in her Mercy books.
The Alpha and Omega series features Anna Latham, Omega mate of Charles Cornick, the son of the "Marrouk" (the alpha wolf of all werewolves). Omega werewolves have the ability to "calm" Alpha werewolves, making them highly prized by the packs. However, they are very rare, which makes Anna the target of another Alpha who covets her abilities. Throw in a fae Gray Lord whose motives and actions are questionable ("never trust the fae") and Hunting Ground is a truly satisfying read.
