Shadowrun (M&M3)

From publisher blurb: Darnel grew up on the mean streets on the South Side of Megatropolis. His single mother works two jobs to keep food on the table for him and his little sister. Darnel could’ve easily fallen in with the wrong crowd. But as luck would have it, he ended up in a small local gym known to train boxers. The owner and trainer Raul "Papa" Santiago, took an instant liking to the polite young man, and offered him a part time job cleaning the gym.
