As a sixteen-year-old, Tessa Cartwright was found in a Texas field, barely alive amid a scattering of bones, with only fragments of memory as to how she got there. Ever since, the press has pursued her as the lone surviving "Black-Eyed Susan," the nickname given to the murder victims because of the yellow carpet of wildflowers that flourished above their shared grave. Tessa's testimony about those tragic hours put a man on death row. Now, almost two decades later, Tessa is an artist and single mother. In the desolate cold of February, she is shocked to discover a freshly planted patch of black-eyed susans--a summertime bloom--just outside her bedroom window. Terrified at the implications--that she sent the wrong man to prison and the real killer remains at large--Tessa turns to the lawyers working to exonerate the man awaiting execution.
