A new war between humans and Arcanics is bubbling to the surface. A rift in the sky has revealed the devastating potential of the long-imprisoned Monstra. And Maika Halfwolf is at the center of it all. In this fourth volume of MONSTRESS, Maika comes closer than ever before to the answers she’s long sought - but those answers carry a steep price. As her friends and allies reveal long-held secrets and shifting allegiances, Maika finds herself at the mercy of the Lord Doctor, a charismatic demagogue whose connections to Maika and Zinn run deeper than anyone could have imagined. Collects MONSTRESS #19-24.
