Billionaire Rake by Misha Bell

He’s a billionaire… and a rake.
Yes, I know it’s not the 1800s. I’m just a bit obsessed with historical romance, that’s all. And books in general, which is why I’m on my way to interview for my dream job at the library when Adrian Westfield’s sheep-like hound knocks me over and into the mud. So I’m late, dirty, and completely flub my interview—only to get the offer of my life.
To win custody of his baby daughter, Adrian Westfield wants to make me his fake wife.
