This is a short book, ostensibly about a short love affair. If I were to simplify it, I'd say it's about a woman who feels she is getting old, the relationship she is dependant on, and the young lover who comes into her life. So far so Mills and Boon, really. But simplifying is not something this novel(la) deserves.
Sagan weaves a tale about emotion, about how some people are slaves to it and about how our love isn't always under our control, even when we see that it's leading us down a lonely path.
I'm purposely steering away from spoilers here, but let me say the lead character of Paule is enchantingly created. I can totally understand why Simon (the young one) falls so totally for her. And she's so well realised that I see why she just can't give in to happiness, even while I'm shouting at her (internally, I'm not a nutter) when she's travelling down the road to a lonely life.
One thing that intrigues me, and I'm sure it's an important point and once it occurs to me I'll understand more, why is there no question mark in the title? Hmmm...
