There's no definitive answer to this question - it depends on what you're looking to get out of Thich Nhat Hanh's writing. If you're interested in his thoughts on mindfulness and meditation, then you might want to start with one of his more popular books like The Miracle of Mindfulness or Being Peace. However, if you want to explore his ideas on social activism andengaged Buddhism, then some of his other works like The Sun My Heart or Vietnam: Lotus in a Sea of Fire might be more up your alley. Ultimately, the best way to figure out which Thich Nhat Hanh book is right for you is to simply start reading and see which one resonates most deeply with your own journey.
