The Perfect Sister

Once inseparable, years of resentment and jealousy have driven Alice and Holly apart. But, though they barely speak these days, Alice knows her sister is hiding something.
When she hears that a discovery at a soon-to-be-demolished apartment building has led police to re-open an 'accidental death' case, Alice thinks nothing of it. She's distracted by a recent chance encounter with a charismatic man named Damien, and the possibility of romance when she had given up all hope. Until someone knocks at her door, with questions about Holly.
Alice doesn't believe her sister is capable of involvement in anything so sinister. But when she tries to contact Holly, she can't be reached...
Forced to dig through the past in order to uncover the truth, Alice starts to uncover years of Holly's secrets - and to doubt her innocence. As the evidence mounts up, Alice has a choice to make: does she want to help her sister clear her name, even if the price is her own future with Damien?
