When she transfers to Shadow Valley U, her dad's brilliant idea has us living under the same roof as newly minted step-siblings, and she becomes impossible to ignore. Too stubborn. Too tempting. Too off-limits. But when I mess up with the wrong crowd, they demand repayment. and unfortunately, they decide Scarlett is the perfect leverage. She deserves a fresh start after what happened at her last school... Instead, she gets me-her stepbrother. The guy who can't stay out of trouble...and can't stay away from her. Protecting her means crossing every line. Wanting her means destroying the rest. Cross the Line is a spicy new adult romance featuring a fighter and his brand new enemy (AKA step-sister), brought to you by the bestselling authors S. Massery and SJ Sylvis.
