Olivia’s Loving Threesome (Healing Hearts Book 1) by Tamara Earthsong

Olivia thought today would be a regular day of work at the restaurant. Instead, she meets a playful couple who capture her interest and receives a handwritten letter. Sealed with a kiss, the letter invites her to a night of bliss. Having recently celebrated their 20th wedding anniversary, Liam and Sana decide to go out for brunch. They didn't expect to fall head over heels for their waitress. The Healing Hearts series is full of characters who truly love and care about each other, supportive partners, amazing friends who help each other heal bit by bit, and lots of steam.
