A spin-off of the Partnership in Blood series.

Thanks to the efforts of Raymond Payet and l'ANS, vampires now have the same legal rights as mortals, and research at l'Institut Marcel Chavinier is focusing on the mysterious partnership bonds between wizards and vampires. But the battle for public opinion rages on. When Detective Adèle Rougier encounters Pascale Auboussu, a shy young woman turned into a vampire against her will, Raymond and Denis Langlois, chef de la Cour nearest the crime, fear a public relations nightmare.

The vampire responsible for Pascale's turning must be brought to justice, but Denis is distracted by an unlikely potential partner—Canadian researcher Martin Delacroix, who is spending a year's sabbatical at l'Institut—and Denis's lingering feelings for his deceased lover prompt him to reject the bond. There's no denying the attraction between them, though, and the allure of companionship is nearly as strong as Denis's grief.

Growing familiarity and yearning for a true mate may induce Adèle and Denis to soften their stances against new partnerships, but Adèle will have to accept a deeper intimacy with Pascale when she has never considered a relationship with a woman, and it will take a near-deadly attack to make Denis admit his most hidden desires. Now he has to hope Martin will be willing to stay.
