When spreadsheets are safer than people, falling in love becomes the ultimate risk in this powerful novel of trauma, healing, and unexpected courage from New York Times and USA Today bestselling author Catherine Bybee.

Luna Canning trusts numbers more than people—and for good reason. As a forensic accountant who specializes in exposing fraud, she knows numbers never deceive, unlike the toxic family she’s spent a lifetime trying to escape. Now living in her grandmother’s Victorian home, Luna has built a carefully ordered life behind walls she thought were unbreakable.

When her car is stolen from an airport parking lot, former FBI agent turned PI Nate Warren steps in to help—and proves more dangerous to her defenses than any thief. Despite Luna’s ironclad rules about mixing business with pleasure, their chemistry ignites, and for the first time, she considers letting someone past her guard. But just as their relationship begins to blossom, Luna’s manipulative mother arrives unannounced, dragging with her a dangerous man and decades of unresolved trauma that threaten everything Luna has built.

Now Luna must confront the ghosts of her past—both metaphorical and possibly literal, as strange occurrences in her historic home suggest she’s not alone. With a violent threat looming and her heart on the line, Luna discovers that sometimes the hardest person to trust is yourself.
