Downlines by Kristin Dearborn

Cassie Freidman has it all. Just ask any of her social media followers. They see her big house, her handsome husband, her perfect children. She's a self-made woman, helping other women be their best girl boss selves, selling fitness drink Serenity. Until one night, Cassie and her daughters go missing.
Cassie's best friend Sarah knows something is wrong. Thinks husband Derek is acting peculiar. She's suspicious of him, but could this actually be worse than a simple family annihilator? Under the blistering Las Vegas sun, Sarah has to figure out where her best friend is, what her husband has done and why, and get out alive.
"I adore Kristin's horror for its deft combination of monsters with a social critique, and she has the perfect eye for capturing the dark side of modern capitalism." - Aimee Picchi
