On the Verge (en Inglés) - T.K. Drake

Teddy Williams was fine where he was. Settled in one city after a lifetime as a military brat, his career as an NHL goalie on the rise...until a mid-season trade throws everything for a loop. A new city and new team are manageable, but finding out you're a Bratva heir to a ruthless empire just as the playoffs are about to begin is overwhelming. The only thing keeping him grounded is Elia. She comes into his life like a whirlwind but turns out to be his calm in the storm. The only problem? She's his teammates' little sister, and her brothers have made it clear she's totally off limits. It's impossible to stay apart, but when even more secrets come to light amidst tragedy, it leaves their relationship on the verge of catastrophe.

Elia Santori is the princess of her family, a bright light in their otherwise dark way of life. She has everything she could ever need as the only daughter of a Mafia boss, but yet...she yearns for more. When a tall, handsome stranger interrupts her usual shift volunteering, sparks fly, and even learning that he's her brothers' teammate isn't enough to deny their attraction. This way of life has a way of catching up to you, though, and Elia isn't immune to the secrets and tragedies that threaten everything she holds dear.
