It's Always the Sister

SHE CAME TO RUIN THE WEDDING. SOMEONE ELSE CAME TO KILL THE GROOM.

Cassie and her older sister Lisa have always been close, especially since their mother killed herself after being defrauded of her life's savings by a Ponzi scheme, and Lisa stepped in to raise Cassie. Now both adults, Lisa is an up-and-comer at EXO Capital, while Cassie is a reporter at a dying business newspaper. Lisa has always reached high, but when her affair with the CEO's son abruptly ends so that he can marry within his station, little details like corporate fraud and Lisa's pregnancy are best dealt with swiftly--and irreversibly.

When Cassie learns that Lisa has fallen to her death from the executive terrace at EXO, she knows that her sister was pushed. Lisa had hinted at becoming a whistleblower, and the official theories of suicide and accident are a bit too convenient. So Cassie does what any good sister would do--she gets herself invited to the son's wedding in Portugal, where she plans to unmask the guilty party in front of his peers. But accountability and justice are elusive after a body washes ashore the morning of the wedding, and all eyes turn to Cassie, who was the last to see the victim alive. As her carefully constructed ruse begins to unravel, Cassie finds that she is a murder suspect. With the help of a journalist, she races against time to find evidence against the true guilty party, to exonerate herself and to secure justice for her beloved sister--or die trying.
