Running Hot (Arcane Society, Book 5)

From Publishers Weekly
A heroine who can see dark energy flashes in a villain's aura and a hero who can squelch villainous thoughts before they're put into action go to paradise to find a murderer, but find love, sex and a nest of drug-enhanced evildoers instead in Krentz's latest Arcane Society novel. Librarian Grace Renquist and ex-cop-turned-bartender Luther Malone, both members of the centuries-old Arcane Society, join forces when the psychic investigative agency Jones & Jones hires Grace, with Luther as her bodyguard, to find a killer in Hawaii. Luther quickly realizes Grace is not your normal paranormal, but their hot romance is put (briefly) on hold as they learn that Nightshade, drug-fueled supernatural baddies, are after the same murderer—as is the lethal psychic hunter La Sirène, an opera diva with a killer voice. The plot is fast, steamy and wildly entertaining even if it defies credulity. Krentzs fans will enjoy this outing and appreciate the teaser that readers have not seen the last of this power couple.

Product Description
Ex-cop Luther Malone, lifelong member of the secretive paranormal organization known as the Arcane Society, is waiting to meet Grace Renquist. Hired as an aura-reading consultant in the quest for a murder suspect, she’s got zero field experience. She’s from tiny Eclipse Bay, Oregon. She’s a librarian, for heaven’s sake.
As for Grace, she’s not expecting much, either, from Malone, who walks with a cane and isn’t so good with a gun. Nice résumé for a bodyguard.
But even before they reach their hotel in Maui – where they’ll be posing as honeymooners – Grace and Luther feel the electric charge between them. Problem is, they need to remain vigilant day and night; because it soon becomes clear there’s more going on here.

Rogue sensitives – operatives for the underground group Nightshade – are pouring into the luxury resort as if there’s a convention. Grace recognizes those dark spikes in their auras. And she understands how dangerous these people can be...especially with those para-hunters at their sides.
As Grace knows all too well, if you don’t control your powers, your powers will control you.
