Rules of Dating My Best Friend's Sister

From New York Times bestselling authors Penelope Ward and Vi Keeland comes the second in a series of sexy standalone romances. The last thing Holden promised his best friend before he died was to take care of his sister—but what happens when that "care" is feeling less platonic by the day?

Rule number one for dating your best friend’s sister: Don’t.

Just don’t do it.

Especially when your best friend is dead and the last thing he made you promise was that you’d keep an eye on his little sister, but not too good of an eye. As a musician whose longest committed relationship lasted six weeks, Holden Catalano is the last guy who should be messing around with Laney Ellison. Since childhood, she’s always been off limits.

Though that hasn’t stopped him from thinking about her over the years, especially the times when the two of them would sneak out onto the roof and talk for hours after her brother fell asleep. It was innocent, but Holden’s always held a torch for the brilliant girl he affectionately dubbed “Lala.”

Now all grown up, Lala needs a place to stay after she accepts a temporary research position in New York. Holden thinks he’s doing the right thing by offering her an apartment in the building he co-owns…except having her close by reignites all those old feelings, and things start to get complicated.

Especially since Lala’s engaged.

And especially since, lately, Holden’s noticed something more in her eyes: desire.

He wants her more than he’s ever wanted anything, but he’s being good—on his very best behavior.

Except all good things must come to an end…
