Summary (from Goodreads):
“Katie and Eric Knox have dedicated their lives to their fifteen-year-old daughter Devon, a gymnastics prodigy and Olympic hopeful. But when a violent death rocks their close-knit gymnastics community just weeks before an all-important competition, everything the Knoxes have worked so hard for feels suddenly at risk. As rumors swirl among the other parents, revealing hidden plots and allegiances, Katie tries frantically to hold her family together while also finding herself drawn, irresistibly, to the crime itself, and the dark corners it threatens to illuminate. From a writer with “exceptional gifts for making nerves jangle and skin crawl,” (Janet Maslin) You Will Know Me is a breathless rollercoaster of a novel about the desperate limits of desire, jealousy, and ambition.”
This book is about obsession. That doesn’t really count as a spoiler because if you are one of the best at what you do (as Devon is with gymnastics), it’s your life. It’s a weird combination of your job and your hobby, and it comes first. And, as we learn quickly, it’s also what her entire family (parents and little brother) does, too. Devon’s gymnastic career and her chance to make Senior Elites (which will lead inexorably to the Olympics) is basically the only thing going on with the family. (Yes, the parents have jobs and yes, the brother is good at science but it’s basically filler between training and meets for Devon.)
When it all falls apart, it happens so fast that it’s almost dizzying (both for Katie and Eric and for me as a reader). Everything shatters and it casts everything else into doubt.
(Good luck doing anything else between the start and close of the novel.)
