I have read all of Tamara Thornes books and love her work, but this would be my least favorite of all her books. It seems to drag on slowly, and has too much going on at once. It jumps from aliens, to a crazy end of the world cult, to one former serial killer, to a current serial killer, to a government conspiracy and then to all the romances between the various characters. Oh, and also natural disasters( earthquakes, floods, mudslides).
She's definately one of my favorite horror writers. Keeps you entertained through the complete book.
