Sergei, Volume 2 (Her Russian Protector, #5.5)

Wedding dress designer and boutique owner Bianca Bradshaw always plays by the rules-until Sergei. The Russian behemoth broke down the walls guarding her heart as easily as he kicked down her front door. After a wild, passionate love affair that's the talk of Houston's underworld leaves them facing an unplanned but very much wanted pregnancy, Bianca can't imagine a single day without Sergei in her life-and in her bed. Freed from the clutches of the Russian mob by her tenacious love, former enforcer and prize fighter Sergei Sakharov intends to give Bianca exactly what she wants. He's going to make that luscious, curvy beauty his wife and spend the rest of his life making her happy. Or, at least, that's the plan. But Sergei quickly learns that no one ever really gets out of the life. When unfinished business threatens the family he's trying to build with the woman who forever holds his heart, he'll have to make a hard choice. To protect his pregnant wife, there is no line Sergei won't cross.
