“[Readers] will be rewarded with turns of fate and twists of plot more shocking than even the clairvoyant DeGange may have foreseen.” —The Wall Street Journal“A textbook one-sitting read whose fiendishly inventive details only intensify its remorseless momentum.” —Kirkus Reviews (starred review)“Parks makes suspension of disbelief to his premise accessible via solid prose and characterizations. Readers who enjoy jaw-dropping but credible plot twists will be enthralled.” —Publishers Weekly“This fast-paced novel, narrated in alternating chapters by Nate and Jenny, has twists and turns that’ll keep readers guessing.” —Library Journal“Inventive, well written, fast-paced, and filled with twists.” —The Associated Press“The ongoing battle between the concept of free will and predestination makes Unthinkable so intriguing, along with the mystery behind this strange organization and the nature of their true intentions. Parks has created a dynamic, vivid and incredibly interesting world with Unthinkable.” —Culturess“Charm doesn’t usually figure in mystery-thrillers, yet Parks’s story is loaded with it. It’s the kind of charm that could only be found in a plot about a stay-at-home dad written by, well, a stay-at-home dad.” —Jersey’s Best“Parks’s skill at creating realistic, strong characters makes the twists in Unthinkable believable as they confront evils they didn’t even know existed while proving their inner strength. Nate and Jenny’s unconditional love and respect for each other further buoy the gripping plot. And, yes, Parks makes you believe in predicting the future.” —South Florida Sun-Sentinel“My, oh, my! Brad Parks has done it again! He’s crafted a world-class thriller…This is a story worth reading, hard to put down and a real page turner.” —Virginia Gazette“Unthinkable is an effective and memorable work that will force readers to think hard about the circumstances in which these characters are involved, while wondering what they would do if they were faced with the same challenges.” —Bookreporter“Unthinkable is a driving, single-sitting narrative with twists and turns credibly woven into an engrossing plot.” —Mountain Times“Addictive, thought-provoking, and disturbing, it’s a thumping good read.” —The Free Lance-Star“The strong, taut suspense and the dramatic conclusion make this hard to put down.” —Booklist“The premise demands a big leap of faith, but the payoff is a fun and hard-to-put-down thriller.” —Ellery Queen Mystery Magazine“Unthinkable is a fast, furious, fun and deliciously twisty tale told with the deft and accomplished hand of a veteran storyteller. Nate and Jenny are truly a duo to root for, and there’s a substantive issue at the core of the story about which we should all be better informed. Parks has belted another one out of the park with a focused swing of the bat.” —David Baldacci“A mind bending thriller with a gripping, twisted plot you will second guess until you reach the stunning end. Unthinkable is addictive.” —Melinda Leigh, #1 Wall Street Journal and Amazon bestselling author
