"So I thought I might take up paragliding. You know, buy one on eBay and just jump off the cliff one morning."

Emily Willows is middle-aged, widowed, wealthy, and bored. When she makes those flippant remarks to her son over coffee one Friday, she has no inkling that within a few hours she will be facing the most terrifying situation of her life. Nor could she have guessed that she will be confronting it with the enigmatic young woman who moved in next door a few months ago and who has hardly spoken a word to her since. And neither of them has realized yet that after this meeting, their lives will never be the same again.
