BUTTERFLY EFFECT

Destiny Velora had everything planned for her seventeenth birthday. She'd post the perfect selfie, her followers would shower her with love, and maybe-just maybe-she'd finally hit 10,000 followers. She never imagined she wouldn't wake up to see it.
When the aspiring influencer is found dead in her Crunch University dorm room, FBI Agents Marcus Rivera and Yuna Park are called to investigate what appears to be a tragic accident. But the crime scene tells a different story-one of obsession, manipulation, and a killer who views murder as art.
The contaminated skincare products. The anonymous messages. The fake social media accounts that watched her every move. Someone didn't just want Destiny dead-they wanted to "transform" her.
As Rivera and Park race to identify the killer, they uncover a chilling manifesto and a wall of photographs revealing four more young women marked for death. The suspect calls them "butterflies"-beautiful on the outside, but empty within. And he believes only through death can they achieve true transformation.
With a graduate student's knowledge of chemistry, a stalker's patience, and a zealot's conviction, the killer known as "The Butterfly Killer" has already chosen his next victim. She's seventeen. She was Destiny's best friend. And she has less than twenty-four hours to live.
In a world where appearance is everything and social media is life, someone has decided that the price of beauty is death itself.
