Heart’s Inferno by Georgia Lyn Hunter

He’s a killer…
Through the ages, deadly Guardian Týr watches over the mortal realm with a sword that is as blood-drenched as his soul in his quest for vengeance—his sarcasm a shield for the deepening hell inside him. Until one glimpse of a breathtaking, carefree female stops him dead in his tracks…but she’s the one person he can never have.
Still, she has to be the most exasperating female on the planet, with a tendency to land herself in sticky situations.

She’s happiness incarnate…
Bumping shoulders with intractable immortals is not Kira Smith’s idea of fun. An unfortunate encounter with a certain annoying, über hot warrior undoes all her hard work, and the homeless boy she rescued escapes back into the demon-infested alleys. Kira’s determined to find the child—even if it means tolerating the arrogant, know-it-all as a bodyguard.

For her, he’ll break every rule…
Thrown together in this treacherous hunt, long suppressed emotions unravel. Týr will do anything to claim the woman who stirs his deepest desire and Kira longs to succumb to the happiness she finds in him. But Fate isn’t always kind, revealing a dark destiny that could very well tear them apart…
