Matterhorn (Mac Dekker, Band 1)

"Robbie Steinhardt lives a peaceful life. A fixture of his small alpine village, he tends cattle, minds his own business, and doesn't dwell on his former life and the family and lover he left behind--back when he was Mac Dekker, CIA. But when he learns his son Will died following in his footsteps, he needs answers. What mission took Will up into the alpine heights, and why is Ilya Ivashka on the same trail? Ilya--his close friend, his rival in love. Ilya, who framed Mac for treason and sent him into hiding. Wiping away the years, Mac returns to the field to find the secrets Will hid and finds himself facing the Herculean task of stopping a terrorist plot that threatens thousands. But in a field of double agents, who can he trust?"--
