I’ll Never Tell is a work of historical fiction set during the war years between 1941 and 1945 on the ridges and in the valleys of Eastern Tennessee. Five young people from diverse backgrounds come together to tackle the mystery of a secret city—a so-called “shining city on the hill”—59,000 acres encircled by a barbed-wire fence and guards with guns. The government forced more than 3,000 people in five communities to give up their land, so that a pre-fab city called Oak Ridge could be built. Why did 75,000 workers pledge to keep total silence about what they were doing, promising “I’ll Never Tell?” And why was all this foretold forty years earlier? The novel follows Callie, Saree, Irene, Billy and Jeff as they seek answers to these and other puzzling questions.

A NEW YORK TIMES BESTSELLER From former football player and star of The Bachelor and The Bachelorette comes a fascinating and eye-opening behind-the-scenes look at his drama-filled season on the hit reality show. Before Colton Underwood captured the hearts of millions on The Bachelor, he was a goofy, socially awkward, overweight adolescent who succeeded on the football field while struggling with personal insecurities off it. An All American gridiron hero, he was also a complex, sometimes confused, soft-hearted romantic wondering how these contradictions fit together. Old-fashioned and out of step with the swipe right dating culture of today, he was saving the most intimate part of life for the love of his life. If only he could find her… Now, in The First Time, Colton opens up about how he came to find himself and true love at the same time via the Bachelor franchise. Unencumbered by cameras and commercial breaks, he delivers a surprisingly raw, endearing, and seriously juicy account of his journey through The Bachelorette, Bachelor in Paradise, and The Bachelor. He opens up about being dumped by Becca, his secret dalliance with Tia, what it was like to be the world’s most famous virgin, his behind-the-scenes conflicts with production, and how his on-camera responsibilities as the Bachelor nearly destroyed him after he knew he had already fallen in love with Cassie. A memoir for Bachelor Nation and anyone who believes in the magic of love, The First Time carries a simple but powerful message: It’s okay to laugh and cry and occasionally jump over a fence, if it means coming one step closer to the right person.
