Fireworks: Riley (The MacKenzie Family #3.5)
Liliana Hart

Riley MacKenzie would do anything for his wife, and watching the sadness fill her eyes every time she holds a new niece or nephew is torture. He decides what Maggie needs is a no stress vacation where they can concentrate on—certain bedroom matters. But their vacation ends up mirroring the first time they met in more ways than one, and they realize that spontaneity is sometimes the best way to get what you want.
