Hollow Girl [EPUB ebook] 
The Things Left Unfinished

I need you to trust me one last time — When Hannah fails to save a young girl from a serial killer, the toll of taking on the role of Hollow Girl finally gets too much for her, and she ends up voluntarily returning to Southdown Mental Hospital. But all is not as it appears. Within the hospital, in the secure wing, lies a dark secret — a patient that shouldn’t be there, couldn’t be there, and whose very existence will change everything. Featuring the return of a few familiar faces and a dollop of demonic possession, Hollow Girl: The Things Left Unfinished is written and illustrated by series creator Luke Cooper with a mesmerising cover by Lee Milner (Shift).
