If You Tell a Lie - Lucinda Berry

They never considered how his wife might react, or that by the end of the summer a man would be dead. But Blakely always got her way, and the others followed her lead—even when they knew it was dead wrong.

The girls had been friends from day one at Camp Pendleton, a haven for gifted children. But their senior summer was different. When Mr. Crosby, the handsome tennis coach, wound up murdered after a reckless lie, Blakely, Grace, Meg, and Thera swore themselves to secrecy. And never spoke to each other again.

Until now. Twenty years later a sinister note claiming to know what they did brings them back together. And once again Blakely is pulling the strings.

Unfolding in a dual timeline, If You Tell a Lie is a disturbing journey into the dangerous, sometimes deadly consequences of peer pressure—with a bone-chilling twist you’ll never see coming.
