Mash-Up by S.A. Sommers

Everett
Being a villain wasn’t as much fun as it used to be.
With the DoVA slowly disintegrating, there’s no one to rein in Mash. A perfect world for someone who enjoys their job, cares for their family and loves unfettered destruction. Meeting Levi Underwood was just the icing on the cake.
But something was going wrong. Gaps of time, missing memories, reports of violence beyond his norm started to pile up. After nearly killing a university student–and having no memory of it–being a villain just wasn’t nearly as much fun anymore. Now it was risking lives, Everett’s own included, and jeopardizing his job, his family, and his new relationship with Levi.

Levi
Being an understudy to a superhero was not fun.
Being the identical twin to the city’s second most powerful superhero had serious drawbacks. Having identical powers meant Levi was called in as his brother’s substitute far too often. But at the same time, thanks to the heroes–and villains–he’d met Everett Jameson at the site of of one of their fights. Things went well. Very well.
But Mash was going rogue. He was out of control and out of character. On top of that, the secrets of Granite Jameson and his laboratory were starting to surface. Secrets that could jeopardize his new relationship with Everett.
