The split : a novel
(Book)

"Jane Connor is resigned to being the "plain Jane" of her family—pragmatic and dependable—so unlike her beautiful and impetuous younger sister Esme. When Esme calls Jane during a flash summer storm, announcing she's left her high society husband, Jane is shocked to learn that her sister wishes to stay with her. Could this be an opportunity for them to become close again? The only catch: Esme needs a ride from the city to their small Connecticut hometown, and Jane is terrified of getting on the highway...because of what she did when they were teens. Jane must either let Esme stand on her own two feet for once or jump to her flighty younger sister's rescue—and her choice cleaves her life in two. In one reality, Jane can't overcome her fear and tells Esme to crash with a friend. Twenty-four hours later, her sister is missing. Tortured by regret, Jane dedicates herself to piecing together Esme's life before her disappearance, unraveling a web of lies, broken relationships, and, finally, the truth. In the other reality, Jane swallows her fear and offers her less-than-grateful sister a ride. But while Jane hopes living together in their childhood home will be healing, Esme is aloof and increasingly reckless. The tension between the sisters builds until they are finally forced to reckon with the explosive secret from their past that could destroy their fragile bond—and both their lives"--From publisher website.
