"In a well-crafted debut, Smith-Blum provides the reader a ringside seat to the birth of the nuclear age...a beautifully written, important story...Tangles packs a punch and hits close to home." -Robert Dugoni, New York Times bestselling author of The Tracy Crosswhite Series

Oppenheimer was just the beginning.

When a harpooned whale offers proof the Hanford Nuclear Reservation is endangering all life in the Columbia River Basin, Luke Hinson, a brash young scientist, seizes the chance to avenge his father's death but a thyroid cancer diagnosis derails Luke's research. Between treatments, he dives back in, making enemies at every turn. On an overnight trek, Luke discovers evidence that Mary, his former neighbor, embarked on the same treacherous trail, and her disappearance, a decade prior, may be tied to Hanford's harmful practices mired in government-mandated secrecy.

A love story wrapped in a mystery, this stunning Cold War home-front tale reveals the devastating costs of the birth of the nuclear age, and celebrates the quiet courage of wronged women, the fierce determination of fatherless sons, and the limitless power of the individual.

Tangles is a genre-defying must-read for our time.
