Sinopsis
A fatal two-way curse: werewolf blood poisons pure-blood vampires; killing one dooms both. Half-werewolf Ash (unaware) works at Blood Vow for his autistic sister Lia’s bills, meets cold vampire Sebastian—obsessed with Ash’s eyes (like his adoptive mom Eve), Sebastian forces a "sponsorship." Ash’s wolf nature poisons Sebastian; truth: Eve, their shared mom, was killed by werewolves. Only Lia’s blood can break the curse—will they avenge her?
