An American foreign-exchange student arrested for murder. A desperate father determined to win her freedom. The brilliant lawyer tasked with her prosecution. And the sphinx-like young man who happens to be her only alibi. When Lily Hayes arrives in Buenos Aires for her semester abroad, she is enchanted by everything she encounters: the colourful buildings, the street food, the elusive guy next door. Her studious roommate, Katy, is a bit of a bore, but Lily hasn’t come to Argentina to hang out with other Americans. Five weeks later, Katy is found brutally murdered in their shared home, and Lily is the prime suspect. But who is Lily Hayes? It depends on who’s asking. As the case takes shape — revealing deceptions, secrets, and suspicious DNA — Lily appears alternately sinister and guileless through the eyes of those around her. With mordant wit and keen emotional insight, Jennifer duBois delivers a novel of propulsive psychological suspense and rare moral nuance. Cartwheel will keep you guessing until the final page, and its questions about how well we really know one another — and ourselves — will linger well beyond.
