The Only Good Thing Anyone Has Ever Done oleh Sandra Newman

When Chrysalis Moffat and her brother, Eddie, inherit a mansion on the coast of California, Eddie hatches a plan to fleece credulous Californians of their cash by starting the fraudulent Tibetan School of Miracles.

But something else is happening. Through Chrysalis's reunion with her brother, she begins to discover her adoptive father's secret past, causing her own identity to unravel. As Chrysalis lays down the facts of her life, she gambles her identity against the contradictions, half-truths, and fables of her past, leading her ultimately to question what it is we can truly know and whether it is fate or chance that dictates our lives.
