When the Bough Breaks by Denise Grover Swank

For months, Rose has suspected her ex-brother-in-law, has a foot in the criminal world, and she’s equally sure her deceased sister had the evidence to prove it—evidence stolen days just days after Violet’s death.
Those suspicions turn concrete when a body shows up at the construction site Mike works at, and the concrete cracks open wide when her niece and nephew go missing.

Rose might be weeks away from delivering her own baby, she that doesn’t stop her and her best friend, Neely Kate, from looking for the kids. She needs answers and fast, but her search leads her to the man who betrayed her months ago… the father of her baby.
James “Skeeter” Malcolm has been playing games with her for months—refusing to relinquish her paternity but refusing to tell her why. James knows what Mike is up to—Rose is sure of it—but can she convince him to tell help before it’s too late?
