In the previous comic the Joker wasn't really dead and he kidnaps Harley but she escapes and goes back to the Suicide Squad.  Boomerang also comes back. Voltaic joins the Squad. He has the power to harness electricity.  Waller sends them after Red Orchid, Yo Yo's sister,  who has something she wants and who isn't working alone. Things go down badly and not everyone makes it out alive.

Waller uses a secret serum on Deadshot to bring him back from the dead and now the Suicide Squad consists of him, Voltaic, Harley, King Shark, Cheetah, and the Unknown Soldier.  The newest member who doesn't work in the field is James Gordon Junior, a psycho serial killer, who will work with her in analyzing the members and situations.

Their first mission is in Las Vegas where a group of people hope to hypnotize everyone to their message.  Deadshot and Harley are on the ground where Deadshot happens to look at a billboard where the hypnotic tracer was located.  Unknown soldier happened to spot some activity on a billboard and investigated it and found some goons planting the tracer and got rid of them and reported back. Deadshot finds one of the goons on the ground and uses enhanced interrogation to get the information that he works for someone called Mother.  Waller knows exactly who that is and that's bad news especially in who she works with.  Also included are a comic about Harley and a comic about Deadshot. The one about Deadshot leads to volume five.  I loved how the writer put cards under the characters giving their names and a description of them like King Shark. His name is Trixie. Hi likes to Party. or Harley Quinn. Diplomat. or James Gordon Junior. Serial Killer. Analyst. Excitable.  I really love this series.  The introduction of James Gordon Junior really adds to it and I'm very interested to see where it is going to go next.  I give it five out of five stars.
