A mature female scientist protagonist who is a grandmother who works. She isn't/ hasn't been a perfect mom, or maybe she has ? She hasn't been the perfect wife or girlfriend, or maybe she has ? She isn't/ hasn't been the perfect friend or co-worker, or maybe she has ? Why is it so hard to know? Because life's not perfect and neither are the people we love, depend on, armoire or even envy. Why? Because good days follow bad days, but sometimes not in that order. She's a unique heroine and i'm glad Kress wrote her onto the page.
