Womb for Rent — L.J. Smith

Twenty-eight-year-old Carrie Sansone has been losing hope that her streak of bad luck would ever turn around. She's an alcoholic, she's struggling financially, and -- after a stint in rehab following a DUI that totaled her car -- she's desperate to prove to herself and to everyone in her life that she's a good and worthwhile person.

Then a job opportunity falls in her lap: a wealthy couple want her to serve as a surrogate and carry their baby for them. Despite the misgivings of her friends, family, and therapist, Carrie goes ahead with the surrogacy. But the pregnancy and the relationship with the intended mother don't go as expected. As tension rises between her and the intended parents, Carrie's world gets turned upside down, and she must face the truth about herself before she can take on the biggest challenge of her life.

In this novel, a young woman who takes a job as a surrogate mother for a wealthy couple finds herself facing complications from multiple sources, including her own struggles with alcohol.
