Green Lanterns v03 - Polarity (2017)

The acclaimed creative team of writer Sam Humphries and artists Robson Rocha and Eduardo Pansica take Earth's newest Green Lanterns on thrilling adventures around the Earth and across the cosmos in GREEN LANTERNS VOL. 3: POLARITY!
Simon Baz - the Green Lantern who carries a gun. Jessica Cruz - the Green Lantern who struggles with crippling anxiety. They're unlikely Lanterns, unlikely partners and even unlikelier members of the mighty Justice League.
But being members of the world's greatest superhero team also means having to deal with their enemies. Enemies like Dr. Polaris, the master of magnetism, who has just been freed from his imprisonment at the hands of Amanda Waller. Now it's up to Earth's Green Lanterns to stop him before he unleashes his revenge on the entire world.
