Lady Blackwing Battles the Master of the Keys, A Fantasy/Science Fiction Mini - Lady Blackwing, #5

Mercedes is just trying to make her way through life: taking classes, working her shift as a Kaffeteria barista, and writing short stories that she never seems to finish. A minor accident imbues her with startling powers she can't control. She can project future events and rewrite the past but with disastrous consequences. Renters in Mercedes's apartment complex move in and move out with baffling frequency.
Mercedes suspects the landlord is deliberately driving out tenants. But that's only the tip of the corrupt iceberg. Mercedes gets too close to the landlord's evil secret and becomes a target herself. (Be advised that this story contains content that some readers may find upsetting.)
