I've been trying to figure out the title of this book. I'm pretty sure it's Harlequin, but I'm not 100%.

It's one of the funnier romance books. I think it was a fake fiance scenario.

There's a scene at the start of the book in which the hero is either playing around with or walks in and scares the heroine. She falls, hits her head, and gets sick. She ends up with a slight concussion. They end up living together either because she needs a job (possible as a housekeeper) and/or he needs a fiancee.

Does this sound familiar?

Thanks.
