SPY IN THE SADDLE by DANA MARTON,

Two agents must work together without letting a tense past--and a sizzling new attraction--disrupt their most important mission in Dana Marton's HQ: Texas miniseries

It's been ten years since soldier Shep Lewis laid eyes on delinquent-turned-FBI agent Lilly Tanner, and this time they have an even bigger problem than each other: terrorists. In the center of a smuggling operation, Shep and Lilly must partner up and protect each other.

Not even their undercover identities can mask the mounting attraction between the pair as they struggle to survive in the merciless Texas borderlands. Can they put the past behind them and focus on the mission at hand? Or will their partnership reignite the flames of their untapped passions?
