On the hundredth anniversary of being turned into a vampire, Edith joins her adopted daughters and their friends at the Heartsong Clan’s annual “vampires vs humans” LARP recruitment event where she meets an eager Dan Paxton. Dan’s older brother and vampire hunter, Darren, thinks he is merely chaperoning a trip to a nerd convention, but when Darren discovers Dan missing, he follows the only lead he has to the Heartsong Clan’s residence on Tombstone Row. He’s determined to keep his Hunter instincts in check, rescue his brother, and make a clean escape. When an impromptu late-night encounter leads Darren and Edith to be honest with each other about who and what each of them are, Edith longs to keep Darren and his brother close, even though it goes against Clan rules. The two start to grow closer as they seek out the truth from Edith’s Sire, Mr. Heartsong, and soon Darren is finding it harder than he thought to snuff out Edith and her family.
