Enemy Infiltration by Carol Ericson (Mass Market Paperbound)

She'd lost her brother. Can a jaded Delta Force soldier help her find out why? Strong-willed Lana Moreno won't rest until she finds out the truth about her heroic brother's death. And neither will Logan Hess, whose covert government mission soon becomes entwined with another goal: protecting Lana. On Logan's Texas ranch, these unlikely partners are fighting to understand what really happened overseas while sparks ignite between them. But their investigation quickly provokes a firestorm of consequences--and attention from all the wrong people.
