OUT NOW! Love and the Undead by Eve Morton
Mike’s brother Zach has always been a little weird. He spends most of his nights sneaking out to hunt for ghosts, and then reading fan fiction for his favorite TV show Paranormal whenever he has free time. But when Zach comes out as gay, and is subsequently bullied at school, Mike realizes his brother needs an ally more than anything. Though Mike knows he’s also pretty strange, they form a pack with other outcasts at the school to make their time spent in high school a little better.
Everything changes when Ray, a new student, shows up at the school. Mike breaks away from his brother and soon falls for Ray — while at the same time unearthing a mystery about their small town. As teachers disappear and dead bodies pile up, Mike and Ray are left alone fighting evil, when all Mike wanted to do was fall in love.
