One could write an entire dissertation on the cover of this issue alone; what a beautiful piece of art, worthy of getting hung on a museum wall. Readers will also be glad to have judged the book just by the cover, as its content is just as great. The final chapter of "Hydrology" marks the defining face-to-face between Batwoman and La Llorona. What a nice way for Kate to finally be at peace with herself for what happened to her sister; this epiphany makes the character move forward and grow, not only as a person, but as a hero a well. This issue also opened the gates for the title to expand its horizons in multiple directions, as Batwoman is forced to make a hard choice in order to continue her mission, and a warning from a guest star in the final pages, creates a sense of inevitability for what's to come. That last line of this issue, that promise, was the best part of the whole thing. Excellent arc! Next: Amy Reeder joins the series.
