Sam I Am (October Trilogy, #1)

Seventeen year-old Logan Wright has always turned to the make-believe world of her written words to escape the pain of her real life. Through her writing, she lives vicariously, creating gorgeous but dangerous male characters who hunt down, and fight for, their chosen mates. For a vice, it's a safe one. Normally.
However, this is October.
The moon is full, the cemetery is filled with mists, and the misspoken words of an ages-old spell have released an ancient force. It is shapeless - nameless. Until it happens upon the words of a beautiful young bard and takes the wickedly handsome form of one of her creations.
Now Logan finds herself the object of desire for a boy who appears to be everything she ever dreamed of. Sam Hain is tall, strong, and gorgeous. He wants her; there’s no denying that. So, what’s the problem?
Sam’s kisses come with sharp teeth – and a dark promise.
Logan, her friends, and her long-time crush must band together in order to save her from the force they unwittingly awakened. They have one month. And it’s going to be a long one.
