Such a Good Liar

Summary

Fake it till you kill them
Lydia has arrived on an exclusive Caribbean island populated only by the ultrarich.
The Harrington sisters rule the island, throwing lavish parties and treating everyone around them like toys for their amusement. Lydia simply can’t wait to meet them.
That’s because Lydia’s not really Lydia.
And the Harringtons have hell to pay for what they’ve done.
When a storm hits the island and cuts off all routes to the mainland, Lydia is given the perfect opportunity to exact revenge for her mother’s death. But with time running out and her identity about to be exposed, will she be able to carry out her deadly plans?
