All & Nothing (Broadway #1)
Allie York

Ewan Alexander has one woman in his life--his little sister, Amelia. But then his disobedient dog, Clark, crashes into Jovie, a dog trainer, and their attraction is immediate. Despite their reservations, Jovie and Ewan fall victim to the chemistry between them and the relationship heats up quickly.
The couple, along with Amelia, ease into a comfortable rhythm until someone else changes the game.
Someone deadly.
And he wants Jovie.
