The (Secret) Baby by Leddy Harper

Maid of honor Kelsey Peterson is disappointed when the bride-to-be bails on her bachelorette party—especially since Kelsey’s already ordered the stripper. Desperate for a break from her romantic woes, Kelsey goes through with the party. After all, why let a good stripper go to waste?
Dr. Aaron Baucus is definitely not a stripper. He’s a legit doctor with a PhD in neuropsychology. But when his friend calls him over to a bar to meet a bunch of tipsy, flirtatious bridesmaids, they assume otherwise. After all, their stripper was supposed to be dressed like a doctor. Aaron isn’t much for pretending, but with Kelsey, he’s willing to be whatever she wants him to be. At least for one night.
But fate has a wicked sense of humor: Aaron and Kelsey are the maid of honor and best man at the same wedding. And after their one-night stand, Kelsey’s pregnant, but she doesn’t know how to tell him. Aaron wants to start a relationship, but he doesn’t think Kelsey wants something long term. Can their fragile romance survive all the half truths and secrecy?
