Marriage of Inconvenience: (a bwwm romance) (SEALs and Sorority Sisters Book 4) by Alexandra Isobel

Her Guardian. His Burden. Bound by a bond forged in youth, the boy who guarded her wild spirit must now protect her as a man does a wife. Marcus has been dealing with Samara since they were kids…except now she’s not a kid anymore. She's a beautiful distraction he can't afford. And the trouble she's tangled herself up into this time, could knock him—an elite sniper off his game. Getting married to keep her in the country was supposed to be the solution. Instead, having her as his wife is now the basis for all his problems.
