Keith Rees book launch at Malvern Books. In Rees’ new novel, "One Night in Bangkok," Miles Devereaux — a working-class family man — is thrust 60 years into the futuristic world of 2065 Bangkok. While trying to figure out the mystery of his time travel and how to return home, he’s also playing a life-and-death game of chess in which the players and pieces’ fates are reliant upon each player’s acumen. The science fiction piece is projected to be the first installment in "The One Night Trilogy." He’ll speak and sign the book. 7 p.m. Saturday. Free. 613 W. 29th St. malvernbooks.com.
Magna Carda homecoming show at the Parish.

This show packs extra ATX hip-hop heat with Kydd Jones, M3cca and Troy Bishop filling out the bill. 9 p.m. Saturday. $7 in advance. 214 E. Sixth St. theparishaustin.com. — Deborah Sengupta Stith
