Detour by James Siegel

Second Hand 

Central Park, New York. It was the small girl chasing a pink balloon that had given Paul and Joanna the idea; to end five years of failing to conceive, and to adopt. Which is why they are travelling to the Santa Regina orphanage in Columbia, to meet their new daughter, Joelle.

It is meant to be a new beginning in their lives. But it is not the new beginning they were expecting.

Columbia is a dangerous place, particularly for a foreigner with a wife and daughter to protect. Paul would do anything for Joanna, and now he is going to have to. He's got eighteen hours to get a deadly consignment to an address in New York. He dare not be late. He dare not dial 911. Because if the delivery doesn't arrive, he'll never see his newly created family ever again . . .
