Parents need to know that Blessed Monsters is the third and final book in Emily A. Duncan's Something Dark and Holy trilogy. After the betrayals and life-ending mistakes on the mountain at the end of Book 2, Ruthless Gods, the 100-year-long war between Kalyazin and Tranavia (fantasy analogues for pre-Industrial Russia and Poland) rages on, and Nadya, Serefin, Malachiasz, and their friends end up in Komyazalov, the capital city of Kalyazin. There, they plot to prevent the world from being devoured by newly awakened ancient, fallen gods and maybe end the war, too. Violence is, at times, bloody and intense. Human characters use daggers, swords, and magic, as well as hand-to-hand fighting, while gods in the form of monsters use hands, claws, and teeth to defend, injure, and brutally kill. Adult couples share passionate kisses, grope under skirts and without shirts; sex is largely implied, not described. The characters swear with moderate regularity, including "f--k," "s--t," "ass," "damn," and "hell." Characters drink wine and vodka several times, though not excessively. Publisher recommends this for age 13 and up, but given the level of violence, 15 is a more appropriate floor.
