The Hunter's Vow. Children of the Wildings, #1

One outlaw, two hunters who don't want to fall in love, and a thousand-year-old mystery. Blake Vendine, mage and bounty hunter, has made it his life's mission to hunt down lawless, wicked men like the ones who nearly destroyed his family when he was a child, and bring them to justice for their crimes, no matter the cost to himself. During his search for the notorious con man and renegade mage Wiley Wedlin, he crosses paths with a woman named Comfort who wants to find Wedlin just as badly as he does - for completely different reasons.
After a difficult childhood being raised in saloons by her good-time-girl mother, Comfort Garvin is in search of a better life. And the key to that better life is a man named Wiley Wedlin. After years of futile searching, when she comes across a bounty hunter named Blake Vendine who is also looking for Wedlin, she knows her luck has finally changed. Blake doesn't want anyone tagging along on his hunt, but, looking down the barrel of Comfort's revolver, he realizes he doesn't have much of a choice but to let her join him.
He definitely doesn't want to fall in love with his unwanted companion and rival, and Comfort returns the sentiment - but they soon find they might not have much choice about that, either. And just as Blake and Comfort find a hot lead on Wedlin, a thousand-year-old mystery comes to life and changes everything. A new series in the Wildings world, featuring the next generation of the Vendine family, filled with magic, adventure, and romance.
Children of the Wildings comes after Daughter of the Wildings and Defenders of the Wildings. It is a self-contained story, but is best enjoyed after reading Daughter and Defenders. Contains language, violence, and adult situations.
