Quote
"The vampires and shapeshifters known as the Others leave the humans they consider “clever meat” alone, as long as the humans provide them with manufactured goods and do not encroach upon the natural resources that the Others control. Now, in a book that earned nearly 7,600 five-star Goodreads.com ratings, a group of rogue humans is leading violent attacks against the Others in a land grab, unaware that they are provoking even more dangerous forces. Locus calls it “scary and charming.”
Book 1 in the series "Written In Red" is also discounted/available for $2.99
