Unexpected Surprises: A Corbin's Bend Valentine's Day Novella (Love in the Rockies #5)
Ruth Staunton

When Grant hears this, he insists that she is working too hard and needs to cut back on the things she has committed to, the first and foremost being the Valentine's Day dance. Lainie insists that she can't do that and finally he reluctantly agrees to let her work part of the dance and then come home.
Under extreme protest, Lainie agrees, but when the time comes to admit to her supervisor that she can't chaperone, she changes her mind and decides Grant is being unreasonable. She determines to chaperone the dance anyway and deal with Grant later. Unfortunately, Lainie's plan doesn't work out quite like she intended it to, and she is in for quite a few unexpected surprises.
