Project Threshold: Team Berger: Division 1 by Craig Crawford

In a multiverse where the walls are thin between our world and others, Project Threshold stands between humanity and monsters crossing over to threaten us. Harris Berger and his team intervenes on our behalf. Death waits around every corner but dying isn’t the worst thing they have to endure. Berger wades in with his team: Sam, Billy, Jacks, Jessie, and their new recruit, Pendelhaven. Team Berger faces an unknown advanced civilization, mimics loose on the streets of Chicago killing homeless people, dealing with the aftermath of witnessing awful things, mermaids in the Midwest and an apartment where people start committing suicide for no apparent reason.
