A little long, but compensated by cutting into small chapter and the promise of an end in apotheosis

I'm hooked on the start, the first part is involved, it attaches to the character.
Then, in Paris, it's a bit long, but the division into small chapter allows to hang on.
The ending is surprising, in fact many things in this book.

It seems slow, but you also need to take time to digest and integrate everything that the characters live. This is not just a sequence of actions, but especially complex feelings that take the time to grasp.
But time is what we lack badly today, so reading so forced march is a little hard.
