Never Wave Goodbye by Doug Magee

It's an emotional morning as Dr. Lena Trainor sends her daughter, Sarah, off to summer camp for two weeks. The camp is picking up Sarah and her best friend, Linda, at their homes. But after Sarah leaves in what Lena believes is the camp van with a man named J.D., Lena discovers that she's been kidnapped along with Linda and two other boys who were going to the same camp. Soon, a million dollar ransom is demanded from the parents with the FBI being called in. The parents, though, don't entirely trust one another or the FBI and wonder who's behind the kidnappings (they even suspect each other). Told from the point of view of the parents, children, and kidnappers, Never Wave Goodbye is a page turner with an interesting twist and story that makes it a good read. Read-alikes would be C.J. Box's Three Weeks to Say Goodbye and Fear the Worst and Never Look Away by Linwood Barclay.
