Past and present collide in an atmospheric mystery about two best friends and the man whose lake house means something different to them both--from "a great new voice in fiction" (Emily Giffin).This is the moment that Leah Tessaro has been waiting for- her boyfriend, Ollie, is taking her and her best friend, June, to his family's lake house for a week of lazy summer bliss, boating and barbequing. Leah can feel in her bones that this vacation will be the moment he finally proposes. And she can't wait to share that joy with June, whose presence will make everything feel more real. Seven years later, the moment June Kang has been dreading has finally arrived- her fiance, Ollie, is taking her to his family's house on New York's Seneca Lake. But this is not an ordinary house, on an ordinary lake; it is haunted by June's long-buried memories of her lost friend, Leah, and by all that Leah meant to the man June loves more than anything.Alternating between the two women's vibrant voices, one in the present and one trapped in the past, Seneca Lake explores a complex tangle of friendship, loyalty, and betrayal, all driving toward one question- what exactly happened to Leah on that hot summer night?
