Suicide Squad Most Wanted Katana TPB

In these stories from SUICIDE SQUAD MOST WANTED: DEADSHOT/KATANA #1-6, Katana needs to know more about Soultaker's origin if she's going to have any hope of controlling the sword instead of falling under its influence. Dr. Helga Jace, a Markovian astrophysicist, may be able to shed some light-but before Katana can get the info, Kobra's forces attack!
