SEAL of Refuge by Alyssa Bailey

Alesha loves her Alaskan island home, but two years after a painful breakup, she is still overly cautious when dating men. When a widowed Naval officer extricates her from a sticky situation, they find an instant attraction, and he steals her heart. He seems too good to be true. That’s because he is.
When the Navy offers SEAL Commander Zayden Wellesley the career opportunity of a lifetime, he accepts. Finally, things are looking up. He likes to do things orderly, and by the book, unfortunately, raising children, a SEAL’s life, and dating, rarely follow the rules. Alli doesn’t. Things are finally going according to Zed’s plan except for one little snag: he neglects to inform her he has roommates.
Soon, Zed is scrambling to protect his own, save his career, and secure his relationship before it’s too late. When things don’t go to plan and danger threatens all he holds dear, it will take the Guardians’ training and expertise to get them through safely. He has learned to roll with the punches, can Alli?
