Knocked Up By The Billionaire by Tasha Fawkes, M.S. Parker

Brady Shaw is the sole heir to a billion-dollar oil empire in Texas. However, he has no desire to take over the family business. He’s too busy pandering in women, booze, and all of life’s other temptations.
When his father shuts down the flow of money, Brady is presented with an ultimatum: marry and produce a grandchild within a year, or spend the remainder of his life like the rest of the world—poor as fuck.

Dana Sommer is a hard-working college student down on her luck. After losing her scholarship due to budget cuts, she now must find a way to, not only pay her tuitions, but also get her hands on $50,000 to settle her brother’s gambling debt, or she could lose the only family she has left.

To resolve her impasse, she answers a Craigslist ad with a very unusual offer that could solve all her problems—marry a rich, spoiled playboy for one year and bare his child. The reward? Half a million dollars.
