Six Weeks by T. Spear

Six Weeks.
A new beginning.
Blair Young is taking a leap of faith to save her marriage and bring stability to her home life. When her husband refuses to get another job to do what is right for their family, Blair does the unthinkable.
She joins the Air Force.
Boot camp turns out to be exactly what she needs to realize how strong physically and emotionally she can be, and she makes connections which change her life. Including the support of her attractive instructor, who becomes more than she asked for.

Sergeant Jake Brigham is welcoming another class of recruits. Every six weeks, a new set of faces, ready to be taken under his wing, show up for basic training. This group seems exactly like the rest of them, wide-eyed, and ready to be taught how to handle the real world.
Except for her.
Jake must remember he’s here to teach, to bring out the best in those under his purview—not get into a personal relationship, let alone a romantic one. But when the unexpected happens to Blair’s family, Jake gives her a shoulder to lean on and the courage to push through towards a brighter future.
As graduation day draws near, will Jake have the strength to say good-bye?

Six weeks is only supposed to be the start of her new life with her family, but those six weeks shake her world.
