EL used to be human. Now he's a jumble of organs in a bio-suit. EL is also in tremendous pain and has been for a very long time. Hope arrives in the form of Mateo, a mechanice brought in to work on EL's suit. Mateo sees LK in a way no one ever has. And what's more: Mateo offers EL an escape. Hollow Heart reunites Tet creators Paul Allor and Paul Tucker for a queer monster love story about the choices we make between giving our loved one what they want and what we think they need.
