Hearts of ShadowPaperback - 2013
"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 or 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. Soon the only chance Leif and Grace will have to save their world will be a dangerously fragile link that could forever unite their souls--or consume everything in a storm of destruction"--P.  of cover.
