Now he'll face the devil to keep his vow.

Rip Lockwood, former marine Special Forces and president of the Iron Warriors motorcycle club, swore to protect Deputy Ashley Russo years ago. When she targets her brother's killer--the dangerous leader of a rival club--he fulfills his promise. Their undercover ruse exposes a drug operation...and an unexpected attraction. And they'll risk everything to bring a murderous crime ring to justice.
