Kate Reddy had it all: a nice home, two adorable kids and a good husband. Then her kids became teenagers (read: monsters). Richard, her husband, quit his job, taking up bicycling and therapeutic counseling. Since he no longer sees a regular income as part of the path to enlightenment, it’s left to Kate to go back to work. When she manages to secure a job at the very hedge fund she helped create, she must prove herself (again) at work, deal with teen drama, and try to look after increasingly frail parents as the clock keeps ticking toward her 50th birthday. Then an old flame shows up out of the blue, and Kate finds herself facing off with everyone from Russian mobsters to a literal stallion.
