Batman: The Brave and the Bold #17

Written by Michael Conrad, Torunn Gronbekk and Alex Segura Art by Miguel Mendonca, Christopher Mitten, Fernando Pasarin and Andy MacDonald Leap year only comes once every four years, and for most, an extra day on the calendar is a mild novelty. But for Calendar Man, it's a critical error in that which he holds most dear--and now, Batman and the GCPD respond to a deadly hostage situation, but can they work together to stop Calendar Man before it's too late? Then, Lois Lane dives deeper into a massive conspiracy--but will it swallow her up in the process? And lastly, the Question--with the help of a surprise guest star--unmasks the mysterious villain Zero!
