Undulate

"That was, hands down, the hottest single dad romance I have ever read" (Goodreads). Undulate is a super-spicy age-gap romance between a windowed single dad and his insanely liberated co-worker at the elite adults' club he runs. If you like hot, repressed nerds who are unleashed once they yield to temptation, this one's for you. Monogamous HEA.
