Evelyn Wolfe, black ops CIA intelligence officer, is looking for her kidnapped sister. When the van supposedly holding her sister explodes, Evelyn is knocked out and scooped up by ex-CIA agent and current Ageis Security agent (and former lover) Zane Archer. Archer is out to get Eve for something that happened on their last mission together. Now both are implicated in the bombing that injured several innocent bystanders. When Eve wakes up, she and Archer must set aside their differences while they clear their names and find Eve's sister. Who can they trust? Each other? No one? What really happened on that last mission? So many questions among the flying bullets. Chechynan militants, CIA operatives, security agents, all could be friend or foe and they have to decide together who they can trust before Eve's sister is out of time.
If you like adventure, intrigue, military black-ops stories a la Covert Affairs (TV), Robert Ludlum, etc. You will enjoy Extreme Measures which is part of the Ageis Security series by Elisabeth Naughton.
