The state’s cardinal vampire, Maven, summons boundary witch Allison “Lex” Luther to avoid the killing before it ignites a war. Lex has barely started investigating when she gets another surprise: the biological father she’s never met arrives on her behalf doorstep. He has answers to all of Lex’s queries about her bloodline, but getting those answers could mean betraying the life she’s already constructed.

Then the next vampire is poisoned-and this time around it’s Maven herself. The new bad that hunts Lex is definitely powerful and ruthless plenty of to stop the most powerful supernatural creature in the condition. In order to find such a killer, Lex will have to face down her very own birthright and call on every ally-both living and dead.
