The Alice Network by Kate Quinn
I'm about 2/3 through this one, and I'm not liking it much. I certainly don't understand all of its glowing reviews. None of the characters are very likable. Charlotte, an American college coed, is dissatisfied with the results of the minimal search results for her French cousin who seems to have disappeared during WWII. She comes upon the name of Eve, a female WWI spy, and she hires her to help launch her own search. The story then diverges into alternating chapters of Eve's WWI story and Charlotte's post-WWII story.
I've said it before, and I am saying it again: I do not like the use of divergent timelines as a literary device! Neither do I like a writer who overuses stuttering spelled out in their writing. It feels demeaning to people who actually struggle with speech fluency...especially when it is repeatedly mentioned how simple-minded other characters believe the stuttering character to be because of it.
Edited to add: The afterword indicates that the author's husband (who is a lifelong stutterer) encouraged her to write the spy's stutter and the underestimation of those she came in contact with, and he read and made suggestions along the way. So my apologies for jumping to the conclusion it was somewhat superficial, as I'm now sure that in this case the author's motives were sincere.
Anyway, I am trying to finish this one. I am speedily skimming the spy's chapters, maybe because I don't want to care too much about her when they get to the torture chapters, or maybe because it is just not that compelling.
In case I was unclear, I don't recommend this one. I'm just happy I checked it out from the library instead purchasing it.
