She hadn't turned 40 yet, and already she was over it... Dumped. Pregnant. Fired. For best friends Carmen and Ally, the approach of their 40th birthdays is anything but a celebration. Yet, it might be exactly what they need to set their lives on the right path.  In the bustling heart of New York, Carmen has it all - a high-profile career, a loving family, and a home straight out of a magazine. But as her 40th looms, her life begins to unravel. A surprise pregnancy, a shocking job loss, and the unwelcome sight of crow's feet force her to rethink her perfect life and what it means to truly have it all. Meanwhile, in the quiet of Maine, Carmen's best friend Ally, a spirited marine biologist, confronts her own crisis as she faces the fallout from a doomed affair with her boss. With her romantic life in shambles and her professional life no better, Ally relocates to Portland, Oregon, hoping for a fresh start and one last chance at love. As their individual journeys to happiness lead them in different directions, the strength of their friendship is tested. Tragedy strikes, bringing hidden resentments to the surface and forcing them to confront their past - and each other. In the process, they must answer a pivotal question: Are their best years really behind them, or is turning 40 just the beginning of their greatest adventures?
