Maybe it's just my response, but I find it annoying and wish she wouldn't, given she writes beautifully most of the time. There are the most fabulous descriptions of places and things - for example, this one picked at random describing a village in Spain: "Scarlet geraniums growing in old oil cans, the stripe of light and shade on a white-painted wall, a basket full of tiny silver fish" - so in general I forgive her the occasional clunk and carry on reading.
But. But, but, but. Sentences without verbs or subjects haunt some student manuscripts. It's as if they believe the randomly dividing up sentences confers additional weight to the story. I long to confiscate their full stops and give them a fistful of commas instead. Of course every writer sometimes uses broken sentences for effect, but it has to be a deliberate choice scattered sparsely or else it's simply irritating. And an irritating story to read is one that remains unfinished.
