Unthinkable

"Pregnant with her first child, homicide lieutenant Jane Candiotti is under strict doctor's orders to take it easy. But when a mass shooting claims the life of her teenage nephew, all bets are off. Jane will go to any lengths to bring down the monster who did this-- even enlisting the help of a dangerous ex-con. And when she uncovers a chilling connection between the shooting and a decades old murder case, she knows she cannot stop until the final horrifying pice of the puzzle falls into place."--p.4 of cover.
