Captive by Rafe Jadison

Ex-marine Alex doesn't lose his cool, at least until he meets Roderick, a lawyer with an attitude. When he takes his anger out on Alex, Roderick finds that he has messed with the wrong guy as a grocery store argument soon explodes into a passionate night. But what happens when it's all over? Could the jackass from the grocery store turn out to be something more, or was Alex just held captive?
