Margo and Hank are two teens in tiny, god-forsaken Lazarus, Nebraska. They have a profoundly deep relationship; the only hitch is that Hank has been dead for two months. Somehow he has remained in limbo—no doubt due to the sheer force of their love, and unfinished work to be done. When the pair get tangled up investigating the latest local murder—with Margo doing the everyday detective work and the late Hank spying on suspects unseen—they discover nothing and no one in Lazarus are as they seem. The investigation becomes more dangerous, and it’s up to Hank to protect Margo—as much as a ghost-bodyguard-boyfriend can. While clinging to each other, the teens uncover the sinister secrets of the people they’ve known all their lives, reopen the cold case of Margo’s mother’s death, and learn how to face their past—and how to move on.
