To Sir Phillip with Love by Julia Quinn -- I gave it 4 stars.
Historical Romance, Regency England
Sir Phillip knew from his correspondence with his dead wife's distant cousin that Eloise Bridgerton was a spinster, and so he'd proposed, figuring that she'd be homely and unassuming, and more than a little desperate for an offer of marriage. Except . . . she wasn't. The beautiful woman on his doorstep was anything but quiet, and when she stopped talking long enough to close her mouth, all he wanted to do was kiss her...
Eloise Bridgerton couldn't marry a man she had never met! But then she started thinking... and wondering... and before she knew it, she was in a hired carriage in the middle of the night, on her way to meet the man she hoped might be her perfect match. Except... he wasn't. Her perfect husband wouldn't be so moody and ill-mannered. And he certainly should have mentioned that he had two young - and decidedly unruly - children, as much in need of a mother as Phillip is in need of a wife.

One Small Thing by Piper Vaughn -- I gave it 4 stars.

"Daddy" is not a title Rue Murray wanted, but he never thought he’d have sex with a woman either. Now he’s the unwitting father of a newborn named Alice. Between bartending and cosmetology school, Rue doesn’t have time for babies, but he can’t give her up. What Rue needs is a babysitter, and he’s running out of options. He’s on the verge of quitting school to watch Alice himself when he remembers his reclusive new neighbor, Erik.
Erik Van Nuys is a sci-fi novelist with anxiety issues to spare. He doesn’t like people in general, and he likes babies even less. Still, with his royalties dwindling, he could use the extra cash. Reluctantly, he takes on the role of manny—and even more reluctantly, he finds himself falling for Alice and her flamboyant father.
Rue and Erik are as different as two people can be, and Alice is the unlikeliest of babies, but Rue has never been happier than when Alice and Erik are by his side. At least, not until he receives an offer that puts all his dreams within reach and he’s forced to choose: the future he’s always wanted, or the family he thought he never did.
