Good Half Gone.

For me, the best kind of thriller is one with high emotional stakes, and this fits the bill, featuring a family that’s been torn apart by addiction and an unsolved crime. When they were 15, Iris and her twin sister, Piper, were tricked into meeting older boys, a tryst at which Piper was abducted. The police believed that Piper ran away, the trail went cold, and today lris is a bereft adult, living with her son and grandmother and still wondering what happened to her sister. The twins’ mother, an addict, gave up on finding Piper long ago. But, clinging to hope, Iris has landed an internship at Shoal Island Hospital, a facility in Seattle’s San Juan Islands whose sign has a space where the words “…for the Criminally Insane” used to be. Readers are gradually let in on who she’s there to meet, and along the way, flashbacks return to the time of the abduction as Iris sleuths and grieves in the present day. A closing twist adds fear and drama, but those are present in spades along the way too. This fast read will be a hit with those who enjoy a female-led thriller that features an at-first-powerless protagonist who must seize the reins.
