Confide in Me by Kathryn Denman

Emma Sterling is a self-sufficient, introverted Paramedic, who finally commits herself to spending time with family after dedicating years of her life to saving others. But, when they are targeted for a horrendous attack, she must play into the familiar hands of a sinister criminal to prevent disaster.
Eric Wallace thinks he and his team of Pararescuemen are in for a few standard weeks of training before the annual war games. When the General’s granddaughter arrives on the base, his days go from routine to treacherous. The last thing he needs is an alluring, mysterious woman distracting him from the very real threat to the base.
Together, they lay a trap to take down a sadistic madman. But when a shipment of explosive chemicals goes missing, motives are questions and fingers point in every direction. Their secrets hold the answers they are searching for, but trust is not given easily.
