This week, two of the Current’s most-read articles revolved around people who frequently evoke shudders of revulsion among South Texans: Yolanda Saldivar and U.S. Sen. Ted Cruz.

Selena & Yolanda: The Secrets Between Them, scheduled to run Feb. 17 and 18, will feature a new, wide-ranging interview Saldivar gave from prison.
