This novel was just as brilliant and heartbreaking as everyone promised. Written in almost vignette-like chapters, Lockhart's prose is as stunning as ever. She brings the Sinclairs privileged lifestyle and their vacation homes on a Massachusetts island to life with ease, and the hint of mystery revolving around an accident that causes the main character to lose large chunks of her memory make this book almost unputdownable. 
 The less you know going into this the better, so I won't say much else. Just go read it. And remember the title.
