Last Sons of America #1-4 (2015-2016) Complete

When a biological terrorist attack makes it impossible for anyone in America to conceive children, adoption of kids from other countries explodes. Brothers Jackie and Julian are adoption agents based in Nicaragua. They usually do all their options through legal means, but they’re facing increasing competition from straight-up kidnappers. One desperate move from Jackie could put them in the cross-hairs of some very dangerous people."
