Step into the shoes of a quirky detective named Moxie Heart, who possesses the extraordinary ability to briefly inhabit the hearts of other people and experience their emotions. When a mysterious thief begins stealing hearts—both physically and metaphorically—from the eclectic residents of a strange, surreal city, Moxie must navigate relationships, uncover secrets, and piece together clues from the hearts she explores. But be careful; the more she delves into others' emotions, the more tangled her own heart becomes. Can she solve the mystery before the thief takes her heart, too?
