Cartel Viper by Sabine Barclay

Javier—I may have walk in her door, but I barge into her life. Two reversed numbers lead me to the wrong address. One word and one look are all it takes for me to be hooked. I may lust for her, but I can never love her. She doesn’t need my dark past, deadly present, or likely short future anywhere near her. Now enemies she never imagined are harbingers of death. Will it be hers? Only I make her feel safe. Only I can protect her. You might fear my uncle. But you need to fear me.

Maddy—He doesn’t recognize me, but I know who he is. He’s the one man my family will never approve of. I came back to start over again, and he’s my new beginning. The pleasure he gives me when I’m in his arms surpasses all my fantasies–even the ones he’s in. There’s one major problem. My sister’s married to his enemy. People underestimate me since I’m the nice sister, but I’m silent and deadly. I slide next to you, strike when you’re not looking, and sink my fangs in.

We’re a match made in Heaven because there’s nothing we won’t do for each other.
