Wicked Addiction/Club Wicked Series - Barbara Nolan - Bog

Samson hasn't had many breaks in his young life until local mob boss, Frank Barnett, shows him the ropes. He puts him in charge of the Oasis, a Brooklyn strip club used to wash the mobster's dirty money.
When Lisbeth, a shy redhead, walks into the Oasis looking for a job as a bartender Samson convinces her to strip on stage. Then he can't keep his eyes or his thoughts off Lisbeth's long legs and sweet smile. Their connection is electric-something Samson never experienced with a woman.
Lisbeth never dreamed of being an exotic dancer or falling for the rough, brutal, drop-dead gorgeous, Samson. Her success is immediate and the cash rolls in fast. Everyone's happy except Yvette, Samson's wildly jealous coke-addict girlfriend.
Samson and Lisbeth's steamy, dangerous obsession grows until-
Yvette spins out of control pissing off a rival Russian mobster who threatens to wreck Samson's world forcing him to decide between the woman he wants to save and the woman he wants to love.

Wicked Addiction is Book 1 in the Club Wicked Duet. Samson and Lisbeth's story concludes in Book 2, Wicked Temptation. While either book can be read alone, Wicked Addiction does not have a HEA, and although the story has a conclusion some may consider it a cliffhanger. There are also triggers of violence and suicide, so be warned.
