Upgrade: A Novel by Blake Crouch

An extraordinary group of people helped me at various stages during the writing of this book, and I’d like to take a moment to thank them.

For every redline, for every note, for every time I interrupted what you were doing to bounce an idea off you, thank you, JACQUE BEN-ZEKRY, my editor and partner in all things. You were down in the trenches with me as I tried to wrestle Upgrade to the ground—on the good days, but especially on the brutal ones when I doubted everything. I couldn’t have finished this book without you.

For keeping the faith on the most difficult book of my career, a very special thanks to JULIAN PAVIA, who has been my editor now for three books and seven years. Your insights and instincts are sharper than ever. You are the pressure that makes the diamond.

For the counsel, friendship, (and always epic meals!), thank you, DAVID HALE SMITH, my literary agent now for more than a decade. It’s been quite a ride, my friend.

And thanks to the gang at INKWELL MANAGEMENT, especially RICHARD PINE, ALEXIS HURLEY, NATHANIEL JACKS, and NAOMI EISENBEISS.

For handling my film and television business with pure aplomb, thanks to ANGELA CHENG CAPLAN and JOEL VANDERKLOOT.

For your indispensable support, which allows me to focus on writing by keeping the details of my life in order, thanks to TYSON BEEM, BRANDON KLEIN, MOLLY FIX, and CARISSA GAYLORD.

For being the rocket engine on my books, thanks to everyone at PENGUIN RANDOM HOUSE and BALLANTINE BOOKS, but especially GINA CENTRELLO, KARA WELSH, KIM HOVEY, JENNIFER HERSHEY, QUINNE ROGERS, KATHLEEN QUINLAN, CINDY BERMAN, and CAROLINE WEISHUHN.

For your tireless work on my behalf, and for being the best publicist I’ve ever had, thank you, DYANA MESSINA.

For my beautiful covers on Dark Matter, Recursion, and now Upgrade, thank you, CHRIS BRAND.

For publishing me so well in the UK, a big hug to the incomparable WAYNE BROOKES, and everyone at PAN MACMILLAN.

For reading the ungainly early drafts of Upgrade and sharing your feedback, which improved these pages immeasurably, thanks to my early readers—CHUCK EDWARDS, BARRY EISLER, JOE HART, CHAD HODGE, MATT IDEN, DAVID KOEPP, STEVE KONKOLY, ANN VOSS PETERSON, and MARCUS SAKEY.

A massive, literally-couldn’t-have-written-this-book-without-you bow to the brilliant and witty molecular geneticist MICHAEL V. WILES, PH.D. I learned so much from you. Thank you for your patience, your time, and your deep well of knowledge. You are the gold standard for subject-matter experts. I was so lucky to find you.

For taking a moment to speak with me about quantum computing applications vis-à-vis manipulating genetic data sets, thank you to HOOMAN MOHSENI, PH.D.

For inspiring conversations about the intersection of science and philosophy during the writing of Upgrade, thanks to PHIL WEISER, BRYAN JOHNSON, and J. PIERRE DE VRIES, PH.D.

For helping me find the greatest subject-matter experts on my last three novels, heartfelt thanks to THE SCIENCE AND ENTERTAINMENT EXCHANGE, and especially SACHI C. GERBIN and RICK LOVERD.

For being not only my great local bookstore but one of the great independent bookstores in the world, high fives to everyone at MARIA’S BOOKSHOP, but especially EVAN SCHERTZ, ANDREA AVANTAGGIO, and PETER SCHERTZ.

For your love and support as I worked on this seemingly never-ending book, thank you to my wonderful family—JACQUE, MOM, DAD, my brother, JORDAN, and my three talented, kind, and spectacular children—AIDAN, ANNSLEE, and ADELINE. And a special thanks to AIDAN for all the fascinating philosophical conversations, and especially for pointing me toward The Abolition of Man by C. S. Lewis, which became essential food for thought during the final stretch of the book.

For giving me an amazing life that allows me to do what I love, thank you, MY INCREDIBLE READERS, especially those who’ve been with me since the beginning.

Finally, in 2019, my dearest and oldest childhood friend, BRIAN ROGERS, tragically lost his son, EDWIN ALEJANDRO ROGERS. The character of Edwin Rogers is dedicated to his memory.
