Darkness on His Bones

I enjoyed this very much! It was quite a bit of a dizzying time-travel story, with James and Isidro wandering dreamlike through each other's memories, and it was also a bit of escaping from the bad-guy vampires story, and quite of a bit of what I found the most heart-stopping, the story of their current deadly danger, trapped in Paris at the very beginning of WWI. Lydia's terror and exhaustion, her feeling of guilt over prioritizing her husband's escape over the medical care she can provide, James and Lydia and Simon's helpless love and affection for each other - it was a heartrending read.
