First in a brand new series about a Chicago graduate student's introduction into a society of vampires.Sure, the life of a graduate student wasn't exactly glamorous, but it was Merit's. She was doing fine until a rogue vampire attacked her. But he only got a sip before he was scared away by another bloodsucker-and this one decided the best way to save her life was to make her the walking undead.Turns out her savior was the master vampire of Cadogan House. Now she's traded sweating over her thesis for learning to fit in at a Hyde Park mansion full of vamps loyal to Ethan "Lord o' the Manor" Sullivan. Of course, as a tall, green-eyed, four-hundred- year-old vampire, he has centuries' worth of charm, but unfortunately he expects her gratitude- and servitude. But an inconvenient sunlight allergy and Ethan's attitude are the least of her concerns. Someone's still out to get her. Her initiation into Chicago's nightlife may be the first skirmish in a war-and there will be blood.

Shapeshifters from across the country are convening in the Windy City, and as a gesture of peace, Master Vampire Ethan Sullivan has offered their leader a very special bodyguard: Merit, Chicago's newest vampire. Merit is supposed to protect the Alpha, Gabriel Keene-and to spy for the vamps while she's at it. Oh, and luckily Ethan's offering some steamy, one-on-one combat training sessions to help her prepare for the mission.
Unfortunately, someone is gunning for Gabriel, and Merit soon finds herself in the line of fire. She'll need all the help she can get to track down the would-be assassin, but everywhere she turns, there are rising tensions between supernaturals-not least between her and a certain green-eyed, centuries-old master vampire.

Times are hard for newly minted vampire Merit. Ever since shapeshifters announced their presence to the world, humans have been rallying against supernaturals-and they're camping outside of Cadogan House with protest signs that could turn to pitchforks at any moment. Inside its doors, things between Merit and her Master, green-eyed heartbreaker Ethan Sullivan are...tense. But then the mayor of Chicago calls Merit and Ethan to a clandestine meeting and tells them about a violent vamp attack that has left three women missing. His message is simple: get your House in order. Or else.Merit needs to get to the bottom of this crime, but it doesn't help that she can't tell who's on her side. So she secretly calls in a favor from someone who's tall, dark, and part of underground vamp group that may have some deep intel on the attack. Merit soon finds herself in the heady, dark heart of Chicago's supernatural society-a world full of vampires who seem ready to fulfill the protesting human's worst fears, and a place where she'll learn that you can't be a vampire without getting a little blood on your hands...

Clouds are brewing over Cadogan House, and recently turned vampire Merit can't tell if this is the darkness before the dawn or the calm before the storm. With the city itself in turmoil over paranormals and the state threatening to pass a paranormal registration act, times haven't been this precarious for vampires since they came out of the closet. If only they could lay low for a bit, and let the mortals calm down.
That's when the waters of Lake Michigan suddenly turn pitch black-and things really start getting ugly.
Chicago's mayor insists it's nothing to worry about, but Merit knows only the darkest magic could have woven a spell powerful enough to change the very fabric of nature. She'll have to turn to friends old and new to find out who's behind this, and stop them before it's too late for vampires and humans alike

Turned into a vampire against her will, twenty-eight-year-old Merit found her way into the dark circle of Chicago’s vampire underground, where she learned there was more to supernaturals than met the eye—and more supernaturals than the public ever imagined. And not all the secrets she learned were for sharing—among humans or inhumans.
Now Merit is on the hunt, charging across the stark American Midwest, tailing a rogue supernatural intent on stealing an ancient artifact that could unleash catastrophic evil on the world. But Merit is also the prey. An enemy of Chicagoland is hunting her, and he’ll stop at nothing to get the book for himself. No mercy allowed. No rules apply. No lives spared. The race is on.
