Enjoyable enough thanks mostly to the interesting first third of the story. Sadly, the last third of the book felt forced and trite. The interesting half of the story simply drops off—as if the author tired of that story line or simply did not know how to present it. Beginning a book with two distinct plots and eras tends to promise an eventual convergence of the two, but this happened in an almost simplistic way that allowed the author to give up. With no logical reason, de Rosnay disappoints by ending the one story while staying with the predictable other. It is not as if we learn only what could have been known, as the personal details of that childhood were not known to others. This left me, as a reader, feeling cheated out of what was the more interesting tale.
