From the author of the cult classic Monstrilio, a hair-raising and harrowing story about the very strange, unforgettable day that forces estranged twin siblings to confront their mischievous past. On a quiet morning, Francisca awakes to a rare good day. She skips work, admires the squabbling sparrows on her tiny terrace in Mexico City, and senses a joy so refreshing it feels dangerous. But when there's a knock on her door, announcing an odd stranger at her apartment, Francisca, frightened and fascinated, acts on a whim, shattering her peaceful day and predictable life. She can think of only one person to help her with this unexpected, maybe hostile visitor - her estranged twin brother, Pablo. As Pablo arrives, the day spirals from an awkward reunion into a claustrophobic, feverish confrontation where the twins must reckon with a past they thought they had outrun. Over the course of this peculiar day, Francisca and Pablo realise this man brings devastating questions and a reckoning twenty years in the making. With Gerardo Samano Cordova's trademark blend of strangeness, darkness, humour, and tenderness, IMPS! explores themes of imagination, loss, brokenness, and the quest for the extraordinary in everyday life.
