Elegance of the Hedgehog, The by Muriel Barbery; 2008. Softcover.

Renee is the concierge of a grand Parisian apartment building, home to members of the great and the good. Over the years she has maintained her carefully constructed persona as someone reliable but totally uncultivated, in keeping, she feels, with society's expectations of what a concierge should be. But beneath this facade lies the real Renee: passionate about culture and the arts, and more knowledgeable in many ways than her employers with their outwardly successful but emotionally void lives. Down in her lodge, apart from weekly visits by her one friend Manuela, Renee lives resigned to her lonely lot with only her cat for company.

Meanwhile, several floors up, twelve-year-old Paloma Josse is determined to avoid the pampered and vacuous future laid out for her, and decides to end her life on her thirteenth birthday. But unknown to them both, the sudden death of one of their privileged neighbors will dramatically alter their lives forever.
