An entertaining and insightful pageturner about modern marriage and a tight-knit group of friends navigating their 30s and beyond. It's tradition that on everyone's birthday, the three couples gather to celebrate. They've toasted each other's big life milestones, and been there for each other through loss and disappointment, too. Nathan is the first to turn 40, and when the cake arrives, he makes a shocking announcement. The birthday ritual, and the group of friends, will never be the same again. Confessions follow, and secrets get revealed. One couple's crumbling marriage forces the other two couples to reexamine their own marriages, and the fault lines that lurk beneath. Will their bonds be strong enough to survive issues like infidelity, infertility, and waning passion, plus a series of crises that push each relationship to the brink? The answers may prove surprising. A year after Nathan's big declaration, as the group gathers for the year's final birthday celebration, every person and every relationship will be fundamentally changed. Perfect for fans of Emma Straub, J. Courtney Sullivan, and Rebecca Serle, Reservations for Six is a deeply satisfying novel full of wisdom, humor, and heart. It shines a spotlight on the phase of marriage when the fabric has started to fray, and deftly observes how couples cope, grow, and eventually thrive-together or apart.
