Grace Mercer's unmatched wraith-killing ability made her the unofficial defender of a city shattered by supernatural catastrophe. So there's no way she'll allow the new regent of Seattle's most powerful dragon shifter clan to "protect" her from a vicious evil stalking the ruined streets--and keep her from the freedom she's risked everything to earn. Leif's science-honed instincts tell him Grace is the key to keeping shifters and humans safe. But helping this wary fighter channel her untapped power is burning away the dragon's sensual self-control and putting a crucial alliance at risk.
