The Children Who Time Lost — Marvin Amazon

What happened to the children? The year is 2043, and humans have been mysteriously unable to reproduce for almost thirty years. To prevent panic and keep the population from dwindling to nothing, global authorities offer a Lotto, where a few winners each week can enter a time portal and bring back adopted children from the future. They're never allowed to talk about what they saw. The exception to this system is Los Angeles resident and reluctant celebrity Rachel Harris, the only woman of her generation to naturally give birth. Years of medical tests and treatments have been unable to explain or replicate her pregnancy, and the whole world grieved when Rachel's daughter died in a tragic accident. When Rachel wins the Lotto, she's shocked, and then elated. She can be a mother again. But the baby she meets in 2108 carries a secret that will shatter Rachel's reality and endanger everyone close to her. Now Rachel must race across time to save her life and her child, even as she discovers that nothing-and no one-are what they seem.
