One Spark by Ava McKnight

One Spark has a little bit of everything in it: a husband who is aiming for the top of his company, a neglected wife, and a best friend who is there to help the situation get fixed.

Grace is a domestic goddess in need of being worshipped by her workaholic husband, who is trying to make senior partner. With his focus solely on work, Michael has left Grace lonely and doubting her desirability.
When her former college roommate—the very stylish and statuesque Wilhelmina—stops by the house unexpectedly, she turns a day out by the pool with Grace into an erotic encounter—unwittingly witnessed by Michael! Grace fears the fallout from her tryst, but is Wilhelmina really a catalyst in disguise, the one spark Grace and Michael need to finally confront their marital problems?

Grace is the wife from the One Spark. She is in desperate need for some loving from her husband Micheal, a husband who is a career man aiming to make senior executive in his company. Grace feels lonely, but she does anything for her husband.

One day, after being turned down for sex yet again, her college roommate Wilhelmina unexpectedly comes to visit. These two woman have a history together. During their college days, they both liked to please each other in their dorm rooms. The two woman start fooling around, and unbeknown to them, Micheal catches them. Wilhelmina is able to finally get through to Micheal that his wife needs him to be there for her.

Overall, One Spark is a great read. I love the way the author makes the scenes come alive and makes you want to read this story. In the end, however I wanted to know more, and I didn't want it to end.
