I've recently read Christine Dalcher's Vox, Q and finished Femlandia yesterday. I have really mixed feelings and no one I know has read them - hoping for people on here!
She has some intriguing scenarios but for Vox at least I felt the book fell apart in the last third. In a couple of the books there is an incident in the protagonist's youth which influenced the present day (Q in particular) but it seems a bit too much of a stretch that this was the cause of things (trying to avoid obvious spoilers though happy to stop being cryptic).
Generally I've enjoyed the set up and world building but am not 100% convinced by the way the stories progressed. I'd love to hear other people's thoughts.
