First off, Gotham City Sirens is not as cheeky as the title suggests. It’s written by Paul Dini, a master of the fun and suspenseful superhero story. People who grew up in the 90s will likely remember the Batman series he produced and frequently wrote for. Today’s kids might know him as one of the writers on Cartoon Network’s Star Wars: Clone Wars series. He’s not as heavy and dark as Alan Moore or as trippy as Grant Morrison or as epic as Geoff Johns, but he knows how to craft a good, exciting story that’s usually wrapped up in two or three issues. Here he works with penciler Guilem March, who’s one of the best in the business at the moment. Remember his work for Detective Comics R.I.P.? The reason as to why I recommend this issue in particular is because it forces Harley to talk about her on-again-off-again boyfriend the Joker. She even briefly explains why Joker uses less goofy props these days, and why he no longer drives around in the Joker-mobile. The cliff-hanger ending’s a little cliched, but overall this makes for a pretty good read.
