​Avery Chen died in a cold prison cell, framed by her husband Julian and her own sister. Her last sight was Julian laughing as he suffocated her. But instead of the afterlife, Avery wakes up two years in the past, on the very night of her engagement.​Armed with "future knowledge" of every business move Julian will make and every betrayal Elena will plot, Avery decides to flip the script. She doesn't need a husband she needs a weapon. She approaches the city’s most feared tycoon, Silas Thorne, with a scandalous proposal: “Marry me for 100 days. I’ll give you the Vance empire, and you give me the power to destroy it.”​But as the days count down, Avery realizes that the "heartless" Silas might be the only person she can’t control and her heart might be the one thing she forgot to protect.
