Black Mail by Lynn Raye Harris

Shy Cassie Dixon was never the girl most likely to succeed. Then she moved to the big city, landed a job she’s good at, and started her own YouTube channel for plus-sized girls like her.
When her channel attracts unwanted attention, the threats quickly turn personal—and vicious. But nobody takes the danger seriously. Not even the police.
BDI operative Tyler Scott agrees to check on Cassie when his favorite cousin insists her bestie’s in danger.
The decorated former Marine doesn’t remember Cassie from high school, but one look into her pretty green eyes and he’s got a feeling he’s hooked.
Before he can fight for her heart, he’ll have to fight for her life—and his.
Because someone wants Cassie dead. And they’ve got a foolproof plan to make it happen.
